Two point charges A and B, having charges +Q and -Q respectively, are placed at certain distance apart and force acting between them is F. If 
charge of A is transferred to B, then force between the charges becomes [NEET 2019]
Text Solution
Verified by ExpertsA
The force between two point charges A and B having charge +Q and -Q respectively is given by
… (i)
When 25% charge of A is transferred to B, then new amount of charge on A and B respectively become
So, the force between the two charges now becomes
Thus, the new force between the charges is 
times the initial force between the charges.
