#### If 4 point charges each +c is placed on the circumference of a circle of the diameter 2S if such a way that position of these 4 charges form a square on the circumference of the circle. Then, what is the potential at the center of the circle? Option 1) 4c / S Option 2) 0 Option 3) 3c/S Option 4) S / 4c

As we learnt in
