Loop ABCD and long straight wire are in ...


Loop ABCD and long straight wire are in the same plane. Side CD=2AB. Distance between long straight wire and AB is equal to distance BD. Net force on te loop is:

A

Towards the long straight wire

B

away from the long straight wire

C

parallel to the long straight wire

D

net force on the loop will be zero.

Text Solution

Verified by Experts

The correct Answer is:
B

Magnitude of force on AB`(F_(1))` and magnitude of force on CD `(F_(2))` will be equal in magnitude and opposite in direction.
Hence `overline(F)_(1)+overline(F)_(2)=0` resultant of `overline(F)_(3)+overline(F)_(4)` will be away from the long straight wire.
