QAIPM-2002-Ph-2834: NEET 2002 Physics - Class 11 AIPM-2002-Ph-2834 Solution: A disc is rotating with angular speed \( \). If a child sits on …
A disc is rotating with angular speed . If a child sits on it, what is conserved
Multiple Choice Options
- A linear momentum
- B angular momentum
- C kinetic energy
- D potential energy.
Step-by-Step Verified Solution
If external torque is zero, angular momentum remains conserved.
[External torque is zero because the weight of child acts downward]
L = I _ = constant
