Question
Two concentric shells of masses M1 and M2 are having radii r1 and r2. Which of the following is the correct expression for the gravitational field at a distance r : -


Options
A.
, for r < r1
B.
, for r < r2
C.
, for r1 < r < r2
D.
, for r1 < r < r2
Solution
when r < r1, gravitational intensity is equal to 0

when r > r1,gravitational intensity is equal to
when r > r2, gravitational intensity is equal to

when r > r1,gravitational intensity is equal to
when r > r2, gravitational intensity is equal to
