A wheel having moment of inertia 2 kg-m2 about its vertical axis, rotates at the rate of 60 rpm about this axis. The torque which can stop the wheel's rotation in one minute would be:
  1. \(\frac{2 \pi}{15} N-m\)
  2. \(\frac{\pi}{12} N-m\)
  3. \(\frac{\pi}{15} N-m\)
  4. \(\frac{\pi}{18} N-m\)

Answer

(C) 15 N-m
