A small point of mass m is placed at a distance 2 R from the centre ' O ' of a big uniform solid sphere of mass M and radius R. The gravitational force on ' m ' due to M is F_1. A spherical part of radius \frac{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 F_2. The value of ratio F_1: F_2 is [22 Jan 2025 Shift 1]
