Two Space crafts, X and Y, of equal masses, are falling towards the earth.
A) What are the values of the following ratios
i Wx/Wy
ii acceleration of X/acceleration of Y

B) Why would the astronaut in either spacecraft be considered to be 'Weightless'

PLEASE NOTE: There is a diagram that show Y is 5r (away from earth) and X is 2r (away from earth).

The radius of earth is 6.4x10^6 m

Any help would be very much liked.
Thankyou in advance

Have you ever seen the equations F=GMm/r^2 and F=mg? Those are all you need to solve part a.
