Answer #1

= charge

= charge

d= distance between two charge

F is force acting on each charge.

  we know

   ...........................................(1)

then according to question , charge and distance all change

And new charge

  

New distance  

the new Force is

  

The new force each charge exerts on the other is =

Option (e) is correct answer
