Question

Two rocks, each of mass 72 kg, are positioned 95 m away from each other in deep space. What is the magnitude of the gravitational attraction between them? G=6.674 x 10^-11 N*m^2/kg^2.

3.8 x 10-12N

9.8 x 10-11N

3.0 x 10-10N

3.8 x 10-11N

Answer 1

3.8 x 10^-11N

Step-by-step explanation:

Given

M=72 kg

R=95 m

G=6.67x10^-11

Equation

Fg= 6.67x10^-11((72kg*72)/(95)^2)

Plug into calculator and get

3.8127756 x 10^-11
