Question

expression due to potential due to system of charge​

Answer 1

Answer:

For a number of charges present in space, the total potential at a point due to all those charges will be equal to the sum of individual potential of each charge at that point

Answer 2

Answer:

Electric potential due to a charge q at a point, which is at a distance r from the charge is given as V=Kqr , Where V is the potential due to the charge and K is permittivity of free space. Now, the electric potential at point P will be due two charges (+q and -q).
