Two identical metallic balls with equal charges are kept 4.5 cm apart. The force between both the balls increases by 10% on giving extra charge of 0.001 `muC` to one of the ball. Calculate the charge on each ball.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Understand the initial conditions
We have two identical metallic balls, each with an initial charge \( q \), separated by a distance \( d = 4.5 \, \text{cm} = 0.045 \, \text{m} \). The force between them is given by Coulomb's law:

\[ F = k \frac{q^2}{d^2} \]
