From a solid sphere of mass M and radius R, a spherical portion of radius R/2 is removed, as shown in the figure. Taking gravitational potential V = 0 at r = ∞ , the potential at the center of the cavity thus formed is: (G = gravitational constant)
A
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Potential at point P due to complete solid sphere
= – 
= – 
= – 
= – 
Potential at point P due to cavity part
= – 
= 
So potential due to remaining part at point P = 
=
