Answer:
E. The force on A is exactly equal to the force on B.
Explanation:
The force between two charges is given by

where
= Charge on particle 1
= Charge on particle 2
r = Distance between the charges
k = Coulomb constant = 

This force will be exerted on both the charges equally.
So, The force on A is exactly equal to the force on B
