Question

Mass of a ring is non-uniformly distributed around its geometric centre. If

R is radius of the ring, then

a. centre of mass does not coincide with geometric centre

b. Position centre of mass from the geometric centre will be x (0<x<R)

c. centre of mass will be nearer to the greater mass distribution

d. centre of mass may lie outside the periphery

• A. Only a & b are correct
• B. Only b & c are correct
• C. a, b & c are correct
• D. All the correct

Answer 1

The correct option is A

Only a & b are correct

For a ring of non-uniformly distributed mass, the centre of mass do not coincide with the geometric centre, it will be at a distance of `x` from geometric centre where 0<x<R
