 The centre of mass of an extended body on the surface of the earth and its centre of gravity 

A

are always at the same point for any size of the body

B

are always at the same point only for spherical bodies

C

can never be at the same point

D

is close to each other for objects, say of sizes less than 100 m

Text Solution

Verified by Experts

The correct Answer is:
D
`implies` For objects of sizes less than 100 m centre of mass is very close with the centre of gravity of the body. But when the size of object increases, its weight changes and distance between CM and CG increases.
