How is force between two charges affected when each charge is doubled and distance between them is also doubled?

Explanation

To solve the problem of how the force between two charges is affected when each charge is doubled and the distance between them is also doubled, we can follow these steps:

### Step 1: Write down the formula for the electrostatic force.
The electrostatic force \( F \) between two point charges \( q_1 \) and \( q_2 \) separated by a distance \( r \) is given by Coulomb's Law:
\[ F = \frac{1}{4 \pi \epsilon_0} \frac{q_1 q_2}{r^2} \]
