GM2r
D
4GMr
Solution
Verified by Toppr

V=V1+V2
=+2V1
=2(GMr/2)=4GMr

Q4
A activity of radius R/2 is made inside a solid sphere of radius R. The centre of cavity is located at a distance R/2 from the centre of the sphere. The gravitational force on a particle of mass m at a distance R/2 from the centre of the sphere on the line joining both the centres of sphere and cavity is (opposite to the centre of cavity). [Here g=GM/R2, where M is the mass of the sphere]

Q5
From a solid sphere of mass M and radius R, a spherical portion of radius R2 is removed, as shown in the figure. Taking gravitational potential V=0 at r=, the potential at the centre of the cavity thus formed is (G = gravitational constant)
