Question

The force between two point charges kept at a distance d apart in air is a if the charges are kept at some distance and water how does the force between them is affected

Answer 1

the force in air= F=kq1.q2/d^2
when it kept in water the force becomes
= 80F

Answer 2

Explanation:

As we know that the

f = q1.q2

4πEoKr^2

now,as given

the force between them will be

=> d

f
