Figure shows a yo-yo placed on a rough surface friction is sufficient for pure rolling. After force F acts pure rolling begins

Statement-1: Angular acceleration of yo-yo is in clockwise sense.
Statement-2: Torque due to F must be larger than the torque due to friction.

A

Statement-1 is true, statement-2 is true and statement-2 is correct explanation for statement-1.

B

Statement-1 is true, statement-2 is true and statement-2 is NOT the correct explanation for statement-1.

C

Statement-1 is true, statement-2 is false.

D

Statement -1 is false, statement -2 is true.

Text Solution

Verified by Experts

The correct Answer is:
A
`a=alphaR`

If alpha is clockwise then torque due to F is greaten then torque due to friction
