A square current carrying loop is suspended in a unifrom magnetic field acting in the palne of the loop. If the force on one arm of the loop is `vec(F)`, the net force on the remaining three arms of the loop is

A

`3vecF`

B

`-vecF`

C

`-3vecF`

D

`vecF`

Text Solution

Verified by Experts

The correct Answer is:
B
`F_(BC) = F_(AD) = 0`

`vecF_(AB) = - vecF_(CD)`
