Question

Force between two identical spheres charged with same
charge is F. Ir 50% charge of one sphere is transferred
to second sphere then new force will be:​

Answer 1

Answer:

3/4F

Explanation:

Let the charges be q1 and q2 respectively. Where both are equal.

Now q1'=q1'/2 and q2'=3q2/2(as I added the half from one to another). Now the new Force is F'= KQ1'Q2'/r^2

By doing the math

F'=3/4 KQ1'Q2'/r^2

F'=3/4 F.(F=KQ1'Q2'/r^2
