Question

A and B are two identically spherical charged bodies which
repel each other with force F, kept at a finite distance. A
third uncharged sphere of the same size is brought in contact
with sphere B and removed. It is then kept at mid point of A
and B. Find the magnitude of force on C.
(a) F/2 (b) F/8
(c) F (d) Zero

Answer 1

Answer:

F/2 is the answer of your question.

Aand B are two identical spherical charged bodies which repel each other with force =F

finite distance =

From the figure again, you can see C is placed at

2

r

. Now see the direction of force due to A on C.

F

AC

and force due to B on C F

BC

from simple coulomb's law you can answer as follows
