| ASSERTION: The coil is wound over me metallic frame in moving coil galvanometer. |
| REASON: The metallic frame helps in making steady deflection without any oscillation. |
A) If both assertion and reason are true and reason is the correct explanation of assertion.
B) If both assertion and reason are true and reason is not the correct explanation of assertion.
C) If assertion is true but reason is false.
D) If both assertion and reason are false.
E) If assertion is false but reason is true.
Correct Answer: A
Solution :
Due to metallic frame the deflection on a frame is only due to current on a coil and magnetic field, not due to vibration in the string. If string starts oscillating, due to presence of metallic frame in the field make these oscillations damped.
