Charge `Q` is divided into two parts which are then kept some distance apart . The force between them will be maximum if the two parts are

Options

A. `Q//4`, `3Q//4`
B. `Q//3`, `2Q//3`
C. `Q//2`, `Q//2`
D. `Q//5`, `4Q//5`

Explanation

To solve the problem of maximizing the electrostatic force between two parts of a charge \( Q \) that is divided into two parts, we can follow these steps:

### Step 1: Understand the Problem
We have a total charge \( Q \) which is divided into two parts: \( q_1 \) and \( q_2 \). The force \( F \) between these two charges when they are separated by a distance \( d \) is given by Coulomb's law:

\[ F = k \frac{q_1 q_2}{d^2} \]
