Physics - Gravitation Question with Solution | TestHub

A small point of mass $m$ is placed at a distance $2R$ from the centre ' $O^{\prime }$ of a big uniform solid sphere of mass M and radius R . The gravitational force on ' m ' due to M is ${\mathrm{F}}_1$. A spherical part of radius $\mathrm{R}/3$ is removed from the big sphere as shown in the figure and the gravitational force on m due to remaining part of M is found to be ${\mathrm{F}}_2$. The value of ratio ${\mathrm{F}}_1:{\mathrm{F}}_2$ is
