Assertion Two concentric conducting ring...

Assertion Two concentric conducting rings of different radii are placed in space. The mutual inductance of both the rings is maximum, if the rings are coplanar.
Reason For two co-axial conducting rings of different radii, the magnitude of magnetic flux in one ring due to current in other ring is maximum when both rings are coplanar.

A

Statement I is True, Statement II is True, Statement II is the correct explanation for Statement I.

B

Statement I is True, Statement II is True, Statement II is NOT the correct explanation for Statement I.

C

Statement I is True, Statement II is False.

D

Statement I is False, Statement II is True.

Text Solution

Verified by Experts

The correct Answer is:
A
It is obvious that flux linkage in one ring due to current in other coaxical ring is maximum when `x = 0`(as shows) or the rings are also copanar. Hence under this condition their mutual induction is maximum.
