- 15. Multiple Choice
Calculate the gravitational force between a 15-kg chinchilla and a 65-kg dog which are separated by 0.30 m.
Fg = 3.7*10-8 N
Fg = 1.3*1012 N
Fg = 1.1*105 N
Fg = 7.2*10-7 N
- 16. Multiple Choice
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 Jupiter are 1.99*1030 kg and 6.42*1023kg, respectively.
