Asseration:Lenz's law violates the principle of conservation of energy.
Reason: Induced e.m.f. opposes always the change in magnetic flux responsible for its production.

A

If both asseration and reason are true and reason is the correct explanation of assertion.

B

If both asseration and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution
