Question

PLEASE HELP !!!! Calculate the gravitational force between two objects when they are 0.850m apart. Each object has a mass of 6.00kg.

1. 2.96 x 10^-7
2. 2.22 x 10 ^-9
3. 3.3x10^-9N
4. 2.23x10^-8N

Answer 1

Answer: Choice 3

Formula: Fg = G[(m1•m2)/(r^2)]
Given:
r = 0.850m
m1 = 6 kg
m2= 6 kg
G = 6.674 • 10^-11

Fg= 6.674 • 10^-11[(6•6)/(0.850^2)]
= 6.674 • 10^-11[36/0.7225]
= 3.32545328 • 10^-9
= 3.33 • 10^-9 N
