A rigid body is observed in equilibrium in a particular non rotating, non inertial frame. What can you conclude, if the body is observed from an inertial frame.
Options:(select one or more)
Answer:
B, C, D
Solution:
In the inertial frame, the body translates with the frame acceleration but has no angular acceleration.
Therefore net torque about the centre of mass is zero.
Changing the moment point by a vector parallel to the centre-of-mass acceleration adds r×Ma=0.
Thus the torque is zero for points on the acceleration line and on any line parallel to it.
