Derive an expression for the electric potential in a electric field of positive point charge at distance r.

Two point charges +8q and -2q are located at x=0 and x=L respectively. The location of a point on the x axis at which the net electric field due to these two point charges is zero is

Draw electric field by negative charge.

A hollow charged conductor has a tiny hole cut in to its surface show that the electric field in the hole is n where n is the charge density near the hole

A : The accelerations of electron and proton are different in same electric field. R : Electric force acting on unit positive charge is independent of mass.

How does the electric field lines depend on area ?
