# The magnitudes of the gravitational field at distances r1 and r2 from the centre of a uniform sphere of radius R and mass M are F1 and F2 respectively. ThenF1/F2=r1/r2, if r1<R and r2<RF1/F2=r22/r21, if r1>R and r2>RF1/F2=r1/r2, if r1>R and r2<RF1/F2=r21/r22, if r1<R and r2<R

A
F1/F2=r1/r2, if r1>R and r2<R
B
F1/F2=r22/r21, if r1>R and r2>R
C
F1/F2=r1/r2, if r1<R and r2<R
D
F1/F2=r21/r22, if r1<R and r2<R
