Question

A point charge q is located at the origin. A charge q0 can be placed at a point P1, which is a distance r from the origin (top drawing). Or, a charge 2q0 can be placed at P2, which is a distance 2r from the origin (bottom drawing). All charges are positive. Which statement is true about the electric potentials due charge q at P1 and P2? The electric potential at P1 is less than that at P2, because qo is smaller than 2q0. The electric potential at P1 is less than that at P2, because r is smaller than 2r. The electric potential at is the same as that at P2. The electric potential at P1 is greater than that at P2, because r is smaller than 2r.

Explanation / Answer

You are wrong Anonymous... the right answer is : p1 greater than p2 because r is smaller than 2r
