Statement I: Two coaxial conducting rings of different radii are placed in space. The mutual inductance of both the rings is maximum if the rings are also coplanar.
Statement II: For two coaxical conducting rings of different radii, the magitude of magnetic flux in one ring due to current in the other ring is maximum when both the rings are coplanar.

Options

A. Statement-1 is true, Statement-2: is true, Statement-2 is a correct explanation for Statement-1.
B. Statement-1 is true, Statement-2: is true, Statement-2 is NOT a correct explanation for Statement-1.
C. Statement-1 is true but statement-2 is false
D. Statement-1 is false, Statement-2 is true

Answer

A

Explanation

It is obvious that flux linkage in one ring due to current in other coaxial ring is maximum when x=0 (as shown) or the ring are also coplanar. Hence under this condition their mutual induction is maximum.
