The radius of a uniform sphere is R and its mass is M. The values of the gravitational intensity at distance `r_1 and r_2` from the centre of the sphere are `F_1 and F_2` respectively. Then,

Options

A. `(F_1)/(F_2)=(r_1)/(r_2), if r_1 ltR and r_2lt R`
B. `(F_1)/(F_2)=(r_1^2)/(r_2^2), if r_1 gtR and r_2gt R`
C. `(F_1)/(F_2)=(r_1)/(r_2), if r_1 gtR and r_2gt R`
D. `(F_1)/(F_2)=(r_1^2)/(r_2^2), if r_1 ltR and r_2lt R`

Answer

A
