Q.6
D) 29.4 m/s
A body of moment of inertia 1 = 0.80 kg m about a fixed axis, rotating with constant angular
velocity of 100 rad s', then torque acting on it will be
A) 80 Nm
C) 100 Nm
B) Zero​

Answer 1

Explanation:

As omega is a constant, angular acceleration is zero. Formula of torque is I x alpha. As alpha is zero, torque is zero.
