Two point masses of mass M1 and M2 are dropped from the surface of the earth from point B with A as the centre.[BC and BD are tunnels dug through the earth]
Point C is diametrically opposite to B.
D is a point on the surface such that angle between BC and BD is Ɵ.
M1 is dropped through tunnel BC. It reaches C in time T1
M2 is dropped through tunnel BD. It reaches D in time T2
What is T1/T2???
Assume only gravitational force is present
