Two concentric shells of mass 
and 
are having radii 
and 
Which of the following is the correct expression for the gravitational field on a mass m.
A
for 
B
for 
C
for 
D
for 
Text Solution
Verified by ExpertsThe correct answer is:
B
Gravitational field on a mass m due to outer shell (radius 
) will be zero because the mass is
placed inside this shell. But the inner shell (radius 
) behaves like point mass placed at the center so
