In the arrangement shown in fig. The two point charge are in equilibrium. The infinete wire is fixed in the horizontal plane, and the two point charges are placed one above and the other below the wire. Consifering the gravitational effect of the earth, the nature of `q_(1)` and `q_(2)` can be

A

`q_(1) rarr` positive, `q_(2) rarr` positive

B

`q_(1) rarr` positive, `q_(2) rarr` Negative

C

`q_(1) rarr` Negative, `q_(2) rarr` negative

D

`q_(1) rarr` Negative, `q_(2) rarr` positive

Text Solution

Verified by Experts

The correct Answer is:
B, C
just draw the free-body diagram of both charge paticles and see whether force cam be zero or not on the particle. At least, one force should be opposite to others.
