Electric Potential & Equipotentials

Four point charges each +q is placed on the circumference of a circle of diameter 2 d in such a way that they form a square. The potential at the centre is proportional to

Show answer and solution

Answer: (b)

Each charge is at the radius $d$ from the centre.
$V = 4 \times \frac{kq}{d} = \frac{4kq}{d}$ (a scalar sum, no cancellation).
So $V \propto \frac{q}{d}$ ; the answer is (b).
