APFIVE Gravitational Work Inside a Spherical Shell
A particle is initially at the center of a uniform spherical shell of mass M and radius R. It is then moved to a position just inside the shell, very close to the inner surface. Which statement correctly describes the work done by the gravitational force during this displacement?
A

B
Negative work equal to -GMm/R
C
Work depends on the path taken
D
