An electric charge 1 0^{- 3} μ C is placed at the origin (0, 0) of X - Y co-ordinate system. Two points A and B are situated at (2, 2) and (2, 0) respectively. The potential difference between the points A and B will be:

Solution & Step-by-step Explanation

The electric potential V at a distance r from a point charge q is given by V = \frac{1}{4 π ϵ _{0}} \frac{q}{r} .Distance of point A (2, 2) from origin: r_{A} = (2)^{2} + (2)^{2} = 2 + 2 = 4 = 2 units Distance of point B (2, 0) from origin: r_{B} = 2^{2} + 0^{2} = 2 units Since r_{A} = r_{B}, the potentials at A and B are equal (V_{A} = V_{B}).The potential difference V_{A} - V_{B} = 0 V .
