A mass of 50 kg is placed at the center of a uniform spherical shell of mass 100 kg and radius 50 m . If the gravitational potential at a point, 25 m from the center is V kg m - 1 . The value of V is:

Question

TestHub · Accepted Answer

Use the formula of the gravitational potential in terms of universal gravitational constant, V = - G M R ⇒ V p = - G ( 100 ) 50 - G ( 50 ) 25 = - 4 G .
