Assertion : Force on current carrying lo...

Assertion : Force on current carrying loop shown in figure in `Y` magnetic field, `B = (B_0x)hatk` is along positive x-axis. Here, Be is a positive constant.
Reason : A torque will also act on the loop. brgt

A

If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explanation of Assertion

C

If Assertion is true, but the Reason is false.

D

If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
C
Magnetic field is outwards and increasing with `x`. So, magnetic force wil also increase with `x`. The force on different sections are as shown in figure.

Force will act in positive x-direction. But, no torque wil act.
