Q. Which of the following graphs represents correctly the variation of the intensity of gravitational field $(I)$ with the distance $(r)$ from the centre of a spherical shell of mass $M$ and radius $a$?
A) [image:8_image21.emf]
B) [image:8_image22.emf]
C) [image:8_image23.emf]
D) [image:8_image24.emf]
Explanation
(b) Intensity of gravitational field at a point inside the spherical shell is zero and outside the shell is $I \propto 1/r^{2}$
