Two spherical conductors B and C having equal radii and cayying equal charges on them repel each other with a force F when kept apart at some distance. A third spherical conductor having same radius as that B but uncharged is brought in contact with B, then brought in contact with C and finally removed away from both. The new force of repulsion between B and C isA. `F/4`B. `(3F)/4`C. `F/8`D. `(3F)/8`

Answer» Correct Answer - D
Let charges on B & C be Q then final charges on B and C will be `Q/2` and `(3Q)/(4)` respectively.
