Answer:
The charge on each particle is

Step-by-step explanation:
From he question we are told that
The distance of separation between particles is

The force exerted by on of the charged particle on the other charge particles is

Generally the between these charge particle can be mathematically represented as

Where k is the colombe constant with a value of

Since the charge are identical
So the equation becomes

Making q the subject of the formula

Substituting values
