Question

Two spheres carrying charge q are hanging from a same point of suspension with the help of threads of length 1 m, in a space free from gravity. The distance between them will be _______ (A) 0
(B) 0.5(C) 2 m
(D) cannot be determined.

Answer 1

Two comparable small wads of mass m are swung from silk strings of length L and convey break even with charges q.

The point shaped by the two strings is separated by a nonexistent line, framing edge θ.

Accept that θ is small to the point that tan θ can be supplanted by its surmised meet, sin θ.

The separation between the two charged masses, at harmony, is x.

Demonstrate that, for harmony, x = ((q2L)/(2∏ε0mg))1/3.
