In which of the following cases the centre of mass of a rod is certainly not at its centre?

A

the density continuously increases from left to right

B

the density continuously decreases from left to righ

C

the density decreases from left to right upto the centre and then increases

D

the density increases from left to right upto the centre and then decreases

Text Solution

Verified by Experts

The correct Answer is:
A, B
The centre of mass lie at the centre of the rod if density increases (or decreases) from left to right upto centre and then decreases (or increases) but is equal at equi-distance from the centre.
