What is the gravitational force experienced by an object of 10 kg, 200 m away from an object weighing 1 ton? |
1.6675 N 2.6675 N 3.6675 N 4.6675 N |
1.6675 N |
From Newton’s law of gravitation, we have; F = (G x M1 x M2)/R2 G = 6.67 x 10-11 N m2/kg2 M1 = 10 kg ; M2 = 1000 kg ; R = 200 m F = (6.67 x 10-11 x 10 x 1000) / 2002 = 1.6675 N. |
