Distributed charge of 1 C into two parts such that these part a experience the maximum force when they are kept at a distance of 1 km.

Explanation

To solve the problem of distributing a total charge of 1 C into two parts such that the force between them is maximized when placed 1 km apart, we can follow these steps:

### Step 1: Define the Charges
Let the total charge \( Q = 1 \, \text{C} \). We can distribute this charge into two parts:
- Let \( q_1 \) be the charge of the first part.
- Let \( q_2 \) be the charge of the second part.

Since the total charge is conserved, we have:
