A coin slides over a frictionless plane and across an xy coordinate system from the origin to a point with xy coordinates (1.50 m, 5.30 m) while a constant force acts on it. The force has magnitude 7.40 N and is directed at a counterclockwise angle of 104.° from the positive direction of the x axis. How much work is done by the force on the coin during the displacement?

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?
