How does electromagnetic force affect the chemical properties of an object?
The electromagnetic force plays a major role in determining the internal properties of most objects encountered in daily life. The chemical properties of atoms and molecules are determined by the number of protons, in fact, by number and arrangement of electrons. The configuration of these electrons follows from the principles of quantum mechanics. The number of electrons in each element’s electron shells, particularly the outermost valence shell, is the primary factor in determining its chemical bonding behavior. In the periodic table, the elements are listed in order of increasing atomic number Z. In fact, the forces of electric attraction and repulsion of electric charges are so dominant over the other three fundamental forces that they can be considered to be negligible as determiners of atomic and molecular structure.
How much electron charge is in 4 liters of water?
Noteworthy, in a four liters of water there is about 2.1 x 10 8 C of total electron charge. Thus, if we place two bottles a meter apart, the electrons in one of the bottles repel those in the other bottle with a force of 4.1 x 10 26 N. This tremendous force is comparable with the force than the planet Earth would weigh if weighed on another Earth. Ut, as was written, there are also positive (protons) and these charges tend to cancel each other out.
What is the quantum of electromagnetic radiation?
The photon, the quantum of electromagnetic radiation, is an elementary particle, which is the force carrier of the electromagnetic force. Photons are gauge bosons having no electric charge or rest mass and one unit of spin. Common to all photons is the speed of light, the universal constant of physics. In empty space, the photon moves at c ( the speed of light – 299 792 458 metres per second ).
What is Coulomb's law?
Forces between static electrically charged particles are governed by the Coulomb’s law. Coulomb’s Law can be used to calculate the force between charged particles (e.g. two protons). The electrostatic force is directly proportional to the electrical charges of the two particles and inversely proportional to the square of the distance between the particles. Coulomb’s Law is stated as the following equation.
What is the force of attraction caused by electric charges between particles?
The force of attraction or repulsion caused due to electric charges between particles is also referred to as Electrostatic Force or Coulomb’s Force.
Why is Coulomb's force called Coulomb's force?
Electrostatic Force is also called Coulomb’s Force because the Coulomb’s Law given by French Physicist Charles-Augustin de Coulomb best explains why and how the force of attraction or repulsion between two bodies acts.

Coulomb’s Law is stated as the following equation.
Why is electrostatic force called central force?
The electrostatic force is called a central force because it acts along the line joining two charges.
What is Electrostatics?
Electrostatics is a branch of physics that deals with the phenomena and properties of stationary or slow-moving electric charges. Electrostatic phenomena arise from the forces that electric charges exert on each other and are described by Coulomb’s law. Even though electrostatically induced forces seem to be relatively weak.
What is the branch of physics that deals with the study of stationary electric charges?
Electrostatics is a branch of physics that deals with the study of stationary electric charges.
Why is electrostatic force conservative?
The electrostatic force is conservative in nature because the work done on the charge is independent of the path taken.
What is the term for the phenomenon of slow moving electric charges?
Electrostatics. In physics, electrostatics deals with the phenomena and properties of stationary or slow-moving electric charges. Electrostatic phenomena arise from the forces that electric charges exert on each other and are described by Coulomb’s law.

The net electrostatic force is the force existing when any charge or a particle goes against each other when each vector of each electric force of those respective charges is added together.
How to find direction of net electrostatic force?
The direction of the net electrostatic force is given by ϴ = tan-1 (Fx/Fy)

The force exerted by q2 on q1 is F12 ; since the charge is positive, they attract each other. F13 is the force exerted by q3 on q1. This is also called an attractive force. Here the force points are in different directions, so we the vector components to calculate the net electrostatic force.
What is the force between static charges?
Now that we have an idea about the electric force between these static charges let us go further in more detail about the phenomena. To start with, the electrostatic force is otherwise called as Coulomb force. This is the force exerted by one charge on another when separated by a distance.
What is the force exerted by particles that are lightweight known as?
The force exerted by these particles is known as electrostatic and is mainly described by Coulomb’s law. In simple words, the electrostatic force is the one that exists between charges. Static is means that the charges are not moving fast.
What is the basic phenomenon of static electricity?
The basic phenomenon in static electricity is that the charges are transferred from one body to another. The object that loses charge an electron becomes positively charged, and the one that gains an electron becomes negatively charged.
Why do charges move in equilibrium?
when the charges move extremely slow. The one main reason for charges to be in equilibrium is that they move rapidly because of the strong electric force present.
What is Electrostatic Potential?
The electrostatic potential is also known as the electric field potential, electric potential, or potential drop is defined as
Is the potential energy of a charged particle at infinity zero?
Now, as we know, the potential energy of a charged particle at infinity is assumed to be zero, so the electrostatic potential of an object is calculated for a particle with reference to infinity.
