Question

From a solid sphere of mass M and radius R a spherical portion of radius is removed as shown in figure.
Taking gravitational potential V = 0 at r = oo , the potential at the centre of the cavity thus form is ..............................


where, (G = Gravitational constant)
​

Answer 1

Answer:

From a solid sphere of mass M and radius R a spherical portion of radius 2R 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).
