Question
A massless rod of length 2R can rotate about a vertical axis through its when w centre as shown in the Fig The system rotates at angular velocity the two masses m are at a distance R from the axis. The masses are simultaneously pulled to distance of R/2 from the axis by a force F directed along the rod. The new angular velocity of the system is
- 4
- depends on the value of force F
The correct answer is: 4
