Calculate the gravitational force between a 15-kg chinchilla and a 65-kg dog which are separated by 0.30 m. (G = 6.67 x10^-11 Nkg^-2m^2)
Fg = 3.7*10-8 N
Fg = 1.3*1012 N
Fg = 1.1*105 N
Fg = 7.2*10-7 N
What would the gravitational force be between the Sun and Mars if they were 2.3*1011 m apart? The masses for the Sun and Mars are 1.99*1030 kg and 6.42*1023kg, respectively. (G = 6.67 x10^-11 Nkg^-2m^2)
Fg = 3.8*1015 N
Fg = 2.8*10-42 N
Fg = 1.6*1021 N
Fg = 4.6*10-75 N
