Four charges +q, +q, −q and –q respectively are placed at the corners A, B, C and D of a square of side a. The electric potential at the center O of the square is (1) (2) (3) (4) zero
- A (4)
- B (3)
- C (2)
- D (1)
That's Correct!
It's Wrong!
The electric potential at the center O of the square is zero because the charges at corners A and C are equal in magnitude but opposite in sign, canceling out each other's electric potential. The same is true for the charges at corners B and D. Therefore, the net electric potential at the center O is zero.
