NEET2004PhysicsRotational MotionActual
A wheel having moment of inertia 2 ~kg m ^2 about its vertical axis, rotates at the rate of 60 rpm about the axis. The torque which can stop the wheel's rotation in one minute would be:
Options
- A2 15 ~N - m
- B12 ~N - m
- C5 15 ~N - m
- D18 ~N - m
Correct answer
C. 5 15 ~N - m
Step-by-step solution
Given, I =2 ~kg -m^2 , ₀= 60 60 2 rad / s ₀ and t=60 ~s The torque required to stop the wheel's rotation is aligned & = I l ( ₀- t ) & = 2 2 60 60 60 & = 15 ~N - m aligned
