kAS particle of mass 100 g is kept on the surface of a uniform sphere of mass 10 kg and radius 10 cm. Find the work to bbe dne against the gravitational force between them to take the particle away from the sphere.

Text Solution

Verified by Experts

The correct Answer is:
A
Work done against gravitatioN/Al force to take away the particle from sphere
`=(Gxx10xx0.1)/(1xx0.1)`
`(6.67xx10^-11xx1)/(1xx0.1)`
`=6.57xx10^-10J`
