A Federation starship ( 1.90x106 kg ) uses its tractor beam to pull a shuttlecraft ( 1.80x104 kg )
aboard from a distance of 18.0 km away. The
tractor beam exerts a constant force of
4.0 x 104 Non the shuttlecraft. Both spacecraft
are initially at rest.
1.) how far does the starship move as it pulls the shuttle raft aboard?

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
