QNEET-2018-Ph-883: NEET 2018 Physics - Class 11 NEET-2018-Ph-883 Solution: A solid sphere is rotating freely about its symmetry axis in…
A solid sphere is rotating freely about its symmetry axis in free space. The radius of the sphere is increased keeping its mass same. Which of the following physical quantities would remain constant for the sphere? Angular velocity Moment of inertia Rotational kinetic energy Angular momentum
Multiple Choice Options
- A Angular velocity
- B Moment of inertia
- C Rotational kinetic energy
- D Angular momentum
Step-by-Step Verified Solution
As sphere is in free space and no external torque is acting over it so its angular momentum will
remain constant.
