Four identical spheres each of radius 10...

Four identical spheres each of radius 10 cm and equal mass 1 kg each are placed on horizontal surface touching each other so that their centres are located at the vertices of a square of side 20 cm. What is the distance of their centre of mass from the centre of either sphere?

A

20 cm

B

10 cm

C

`10sqrt(2)` cm

D

5 cm

Text Solution

Verified by Experts

The correct Answer is:
C

The centre of mass would lie at the point of intersection of the two diagonals AC and BD and distance from each of the centre will be `10sqrt(2)` cm.
