The potential produced by a point charge is `V = kQ// r`. Use this information to determine the shape of equipotential surface ?

Explanation

To determine the shape of the equipotential surface produced by a point charge, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Potential Formula**:
The potential \( V \) produced by a point charge \( Q \) at a distance \( r \) from the charge is given by the formula:
\[
V = \frac{kQ}{r}
