A) force
B) torque
C) both a and b
D) inertia
Correct Answer: B
Solution :
Torque \[\tau =\frac{\overrightarrow{dL}}{dt}\] Where L = angular momentum If \[\tau =0\] then \[\frac{\overrightarrow{dL}}{dt}=0\] \[\therefore \] \[\overrightarrow{L}\] = constant So, angular momentum is constant in absence of torque.You need to login to perform this action.
