Answer:
The value is

Step-by-step explanation:
From the question we are told that
The magnitude of the charge of each positive charge for the first case is

The distance between the charges for the first case is

The force between the charges for the first case is

The magnitude of the charge of each positive charge for the second case is

The distance between the charge for the second case is

Generally for the first case the force between the charge is mathematically represented as

Where k is the Coulomb constant with value

So

Generally for the second case the force between the charge is mathematically represented as
