Solution:

Given: Two identical spherical charged bodies A and B which repel each other with force F, kept at a finite distance.

When an uncharged sphere C is brought in contact with sphere B, it will acquire some charge by induction. Due to the repulsion between the two positively charged spheres A and B, they will have less charge on them as compared to their original charge. Therefore, the charge on sphere C will be greater than the charge on spheres A and B.

Now, when sphere C is brought at the mid-point of A and B, it will experience forces from both A and B. Since sphere A and B have less charge on them, the force on sphere C due to A and B will be less than F.

Therefore, the net force on sphere C will be zero as the forces due to A and B will cancel out each other.

Hence, the correct answer is option (c) Zero.

After contact charge on b and c are q/2
let chard on A be +q and B have-a
net force on c
due to A =4kqq/2r*2 =2f
due to B =4kqq/4r*2=f
net =2f-f =f
