At distance 'r' from a point charge, the ratio `(U)/(V^(2))` (where 'U' is energy density and 'V' is potential) is best respresented by :

Options

A.
B.
C.
D.

Explanation

To solve the problem, we need to find the ratio \( \frac{U}{V^2} \) where \( U \) is the energy density and \( V \) is the electric potential at a distance \( r \) from a point charge \( Q \).

### Step-by-Step Solution:

1. **Understand the Definitions**:
- The electric potential \( V \) at a distance \( r \) from a point charge \( Q \) is given by:
\[
V = \frac{kQ}{r}
