1.	All the particles of a body are situated at a distance R from the origin. The distance of the centre of mass of the body from the origin is(a) =R (b) ≤ R (c )>R (d) ≥ R
Answer» (b) ≤ R Explanation: As large number of particles is situated at a distance R from the origin. If particles are uniformly distributed and make a circular boundary around the origin, then centre of mass will be at the origin. While if the particles are not uniformly distributed, then centre of mass will lie between particle and origin. This implies the distance between centre of mass and Origin is always less than equal to R.

Answer»

(b) ≤ R

Explanation:

As large number of particles is situated at a distance R from the origin. If particles are uniformly distributed and make a circular boundary around the origin, then centre of mass will be at the origin. While if the particles are not uniformly distributed, then centre of mass will lie between particle and origin. This implies the distance between centre of mass and Origin is always less than equal to R.
