Four identical spheres each of mass M and radius 10 cm each are placed on a horizontal surface touching one another so that their centres are located at the corners of a square of side 20 cm. What is the distance of their centre of mass from centre of any sphere?

View answer and explanation

Correct option: D

10\sqrt 2 \,cm

Option D (

10\sqrt 2 \,cm

) is correct because it is calculated using the center of mass formula for a system of particles.
