ELECTRIC POTENTIAL AT A POINT DUE TO POINT CHARGE

ELECTRIC POTENTIAL AT A POINT DUE TO POINT CHARGE:-

We can derive this potential at point due to point charge by two methods one is by using gausses law and other is by general methods

By using gausses law

consider a charge. In order to calculate electric flux by gausses law we have to draw 

a Gaussian surface consider a spherical Gaussian surface as shown in fig. Charge is enclosed in it.

GAUSS'S LAW & ITS APPLICATIONS

GAUSS'S LAW:-

Gauss's law is used to find total electric flux and total electric field due to number of charges enclosed by the surface

EXPLANATION & DERIVATION:-

                  Consider a closed surface enclosing number of charges q_1, q_2, q_3,--------- q_n randomly distributed inside the surface then electric flux due to charge q_{1 is}
