The sum of moments of all the particles in a system about its centre of mass is always
Text Solution
Verified by ExpertsThe correct answer is:
B
as 
… ..(i)
If COM lies at origin then, 
From eq. (i), we get
Net moment of all particles in the system about centre of mass 
.
Hence, sum of moments of all the particles in a system about its COM is always zero.
