Gravitational Work Inside a Spherical Shell
A particle of mass m is displaced from the center of a uniform spherical shell of mass M and radius R to a point just inside the shell’s inner surface. What is the work done by the shell’s gravitational force on the particle during this displacement?
A
Zero work is done
B
Work depends on the path taken
C
Positive work equal to GMm/R
D
Negative work equal to -GMm/R
