Q. A body rotates freely about its center of mass when

एक पिंड अपने द्रव्यमान के केंद्र के चारों ओर स्वतंत्र रूप से घूमता है जब

A
Net torque is zero
नेट टॉर्क शून्य है
B
Net force is zero
शुद्ध बल शून्य है
C
Angular momentum is zero
कोणीय संवेग शून्य है
D
Speed is constant
गति स्थिर है

Explanation

If a body is rotating freely (i.e., no external torque), its angular momentum is conserved, and it can rotate around its center of mass. The condition for this is net torque = 0. This allows rotation without changing the motion of the center of mass.
