Breathtaking Electrostatic Formula Sheet

Here you will get all the Electrostatics formulas for class 12 JEE and NEET examination.

Electrostatic formula sheet. Coulombs Law- It states that the electro-static force of attraction or repulsion between two charged bodies is directly proportional to the product of their charges and varies inversely as the square of the distance between the two bodies. These formulae will be helpful in various engineering entrance examinations such as. You can quickly revise entire chapter here in a quick overview.

Our teachers have designed these concept notes for the benefit of Grade 12 students. In contrast if D L the formula above simplifies to V L25cm x Vdisplayed. It is used in the formula for the charged disc charged conductor and an infinite sheet of charge etc.

Coulombs law gives the magnitude of the electrostatic force F between two charges. Infinity is taken as point of zero potential. All Revision notes for Class 12 Physics have been designed as per the latest syllabus and updated chapters given in your textbook for Physics in Standard 12.

Field PHY 2049 Chapter 22 chp22_3doc Electrostatic Force versus Gravity Electrostatic Force. Electrostatic potential is defined as Work required to be done against the force by electric field in bringing a unit positive charge from infinite distance to the given point in the electric field us called the electrostatic potential V at that point According to above definition the electric potential at point P is given by the formula. A capacitor store electric energy in the form of the electric field by the two electrodes of a capacitor one as positive and other as negative.
