Question

What is the distance between a 2000 kg truck and a 3000 kg truck if the gravitational force between them is 0.00006 N?

A 258
B. 567 m
C 981
D. 15

Answer 1

A. 2.58m

Step-by-step explanation:

Using the formula;

F = GMm/r²

M and m are the masses

G is the gravitational constant

r is the distance between the masses

Substitute

0.00006 = 6.67*10^-11(2000)(3000)/r²

0.00006r² = 6.67*10^-11*6000000

0.00006r² = 40.02*10^-5

0.00006r² = 0.0004

r² = 0.0004/0.00006

r² = 6.66

r = 2.58m

Hence the distance between them is 2.58m
