Two identical metal spheres A and B carry same charges q. When two spheres are at distance r from each other, the force acting between them is F. Another identical sphere C is first brought in contact with A, then it is touched to sphere B and then separated from it. Now the force acting between A and B at the same distance is?

    Now the force will be 3/8times of F This is bcoz initially force was kq^2/r^2. Now on touching c to a charges on c and a will be q/2 .when thus q/2charge on c is again touched with B then the charge on b will be 3/4 q . Now the final force will be k q^2 /r^2 ×3/8.thus it is 3/8times that if initial force
