MHT CET 2026 Physics question
Four electric charges + q, + q , -q and -q are placed in order at the corners of a square of side '2r'. The electric potential at a point midway between the two negative charges is
Answer: (A)
Solution
Place the corners in order as with , with , with , with . The midpoint of CD is . Its distance from each negative charge is , and from each positive charge is . Potential is a scalar sum: $V =
