An isolated charge `q_(1)` of mass m is suspended freely by a thread of length l. Another charge `q_(2)` is brought near it `(rgtgtl)`. When `q_(1)` is in equilibrium tension in thread will be

A

mg

B

2 mg

C

3 mg

D

6 mg

Text Solution

Verified by Experts

The correct Answer is:
C
`T-mg=(mv^(2))/(l)" or "T=3mg`

Tension will be maximum at bottommost point.
