Assertion: The coil is bound over the metallic fram in moving coil galvanometer.
Reason: The metallic fram help in making steady deflected without any oscillation.

A

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

B

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

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
A
Due to metallic frame the deflection is only due to current in a coil and magnetic field, not due to vibration in the strings. If string starts oscillating, presence of metallic frame in the field makes these oscillations damped.
