w = 640 N, R = 3r and M = 2m.......
A space traveler weighs 640 N on earth. What will the traveler weigh on another planet whose radius is three times that of earth and whose mass is twice that of earth?

-
W = w (r/R)^2 (M/m) = w (1/3)^2 (2) = 2*640/9 = 142.2 Newtons. ANS.

w = 640 N, R = 3r and M = 2m.
