Answer:
Force between the two charges becomes one fourth of the initial force.
Explanation:
The electrostatic force acting between any two charges is given as,
Here,
F = force
k = Coulomb's constant
= magnitude of charge of the first particle
= magnitude of charge of the second particle
= separation between the two charges
From the above relation,
Thus,
