Two objects with mass m₁=141 kg and  m₂=629 kg are fixed in place at a separation of D=0.120 m.

 

Find the magnitude of the net gravitational force (in newtons) exerted by these objects on a m₃=155kg object placed midway between them. Give your answer in millinewtons (mN).

 

2b 

At an infinitely remote distance, the net gravitational force on the third mass from the first two masses will be zero. Choose True or False for the following statement: "there is a point at a finite distance along the straight line between m1 and m2 where the net gravitational force on m3 will vanish".

 

2c

At what distance from the object with mass m1 (along the straight line between m1 and m2) would the net force on the third mass vanish? Give your answer in meters, and answer 0 if there is no such point.
