Question

Q.1) Derive an expreesion for potential energy of system of two point charges.​

Answer 1

Explanation:

Derive an expression for the electric potential energy of a system of two point charges in the absence of an external electric field. ... i.e., dV=-Edx for unit +ve test charge. Now replacing '+1C' by ′qB′,′dV′ by dW and 'E' by F, we get. dW=-Fdx,dx-displacement between C & B.
