Compute the force of attraction between a 25 kg. mass and a 45 kg. mass that are 9.6 meters apart from center to center.

Answer 1

just plug in your numbers for

F = GMm/r^2

expect a small answer!

Answer 2

25x 45 = 1125

9.6 meters = 9600 km
9600/2 = 4800

1125/4800 = .234375

Answer 3

No. the denominator is distance squared, not halved.

Answer 4

also, don't forget to include G=6.67 * 10^-11 m^3/kg-s^2
