Q. If total external force is zero, then the center of mass

यदि कुल बाह्य बल शून्य है, तो द्रव्यमान का केंद्र

A
Moves with constant velocity
निरंतर वेग से चलता है
B
Accelerates
तेज करता
C
Oscillates
दोलन करता है
D
Rotates
घूमता है

Explanation

This follows directly from Newton’s second law. If total external force = 0, then the acceleration of the center of mass is zero. Hence, the center of mass moves in a straight line with constant velocity (i.e., uniform motion).
