A spherical hole of radius `R//2` is excavated from the asteroid of mass M as shown in the figure the gravitational acceleration at a point on the surface of the asteroid just above the excavation is

In the above question, if the soild sphere is a large rock, what is the gravitational acceleration at a point on the surface of the rock at a point just above the cavity ?

A sphere of radius 2R and mas M has a spherical cavity of radius R as shown in the figure. Find the value of gravitational field at a point P at a distance of 6R from centre of the sphere.

A sphere of radius 2R and mas M has a spherical cavity of radius R as shown in the figure. Find the value of gravitational field at a point P at a distance of 6R from centre of the sphere.

From a solid sphere of mass M and radius R, a spherical portion of radiu (R )/(2) is removed as shown in the figure. Taking gravitational potential V = 0 at r = oo , the potential at the centre of the cavity thus formed is (G = gravitational constant)

A particel of mass M is placed at the centre of a inform spherical shell of mass 2M and radius R. The gravitational potential on the surface of the shell is
