Question

force between two point charges is F.Now if polarity of any one charge is changed then A.magnitude of force will change B.direction of force will change. C.magnitude and direction of force will change​

Answer 1

Hi friend here is your answer.

######################

If polarity of any one of the charge chnages then it will affect only in direction not in magnitude as amount of charge is equal in both case.

If initially , both were positive then 1 polarity changes then Force will change from repulsion to attraction and vice versa.

So there is only change in direction not in magnitude.
