Application +4 | -1

A particle of mass

m

was transferred from infinity into the centre of the base of a uniform hemisphere of mass

M

and radius

R.

What work was performed in the process by the gravitational force exerted on the particle by the hemisphere?

View answer and explanation

Correct option: B

\frac{3 G m M}{2 R}

Option B (

\frac{{3 G m M}}{{{2 R}}}

) is correct because it represents the work done by gravity in bringing the particle from infinity to the center of the hemisphere's base.
