Statement 1: A rectangular current loop ...

Statement 1: A rectangular current loop is in an arbitray oreintation in an external uniform magnetic field. No work is required to rotate the loop abour an axis perpendicular to its plane.
Statement 2: All positions represents the same level of energy.

A

If both statement 1 and statement 2 are ture, statement 2 is the correct explanation of statement 1.

B

If both statement 1 and statement 2 are ture, statement 2 is not the correct explanation of statement 1.

C

If statement 1 is true, statement 2 is false.

D

If statement 1 is false, statement 2 is true.

Text Solution

Verified by Experts

The correct Answer is:
a
`U=-vec(mu)xvecB=-muB cos theta`
Since `mu`, B as well as `theta` constant, U does not change.
