Two tables each have a mass of 29 kg. If the gravitational force between them is 4.24 x 10-10 N, how far apart are they? G = 6.67 * 10-11 N.(m/kg)?
O A. 12.01 m
O B. 11.5 m
O C. 9.55 m
O D. 10.23

B, 11.5m

Explanation:

m=29kg

Fg=4.24x10^-10N

Fg= Gm1m2/r^2       Find r in the equation for how far they are apart

4.24x10^-10=6.67x10^-11(29)(29)/r^2

4.24x10^-10 r^2=6.67x10^-11(29)(29)

r^2=132.29

r=11.5m

Therefore the answer is B
