The gravitational force acting on a particle, due to a solid sphere of uniform density and radius R , at a distance of 3R from the centre of the sphere is F_1. A spherical hole of radius (R//2) is now made in the sphere as shown in diagram. The sphere with hole now exerts a force F_2 on the same particle. ratio of F_1 to F_2 is
