What is the gravitational force experienced by an object of 10 kg, 200 m away from an object weighing 1 ton?
Answer & explanation
Correct answer: option 1
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.
