NEET 2018, Physics Q31: Law of Rotation And Work-Energy Theorem

NEET2018Paper 2018Physics
Q.

Three objects, A : (a solid sphere), B : (a thin circular disk) and C : (a circular ring), each have the same mass M and radius R. They all spin with the same angular speed   about their own symmetry axes. The amounts of work (W) required to bring them to rest, would satisfy the relation

  1. A

    WC > WB > WA 

  2. B

    WB > WA > WC 

  3. C

    WA > WB > WC

  4. D

    WA > WC > WB
