Question:

What is the gravitational force experienced by an object of 10 kg,  200 m away from an object weighing 1 ton?

Options:

1.6675 N

2.6675 N

3.6675 N

4.6675 N

Correct Answer:

1.6675 N

Explanation:

From Newton’s law of gravitation, we have;

F = (G x Mx 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.
