Agroup of scientists is trying to launch an object into orbit, and the object is traveling at 6500 m/s. which best explains why the object will not successfully orbit earth? there is not enough air resistance to keep the object moving. there is not enough friction to keep the object moving. the object is not traveling fast enough to match earth’s curvature. the object is traveling too fast to match earth’s curvature.

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?
