Assertion : A coin is placed on phonogram turn table. The motor is started, coin moves along the moving table.
Reason : Rotating table is providing necessary centripetal force to the coin.

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:
C
Friction provides necessary centripetal force. But if speed increases, the frictional force cannot supply the necessary centripetal force , Therefore, the coin flies off tangentially.
