Due to the mutual synchronous rotation of Pluto and Charon, choose the statement below that best describes what an observer on Pluto would see when looking toward Charon.
a. The observer would always see the same side of Charon, which would appear to hang motionlessly in the same spot in the sky all the time.
b. The observer would always see the same side of Charon, which would rise and set as it orbits Pluto.
c. The observer would see Charon rotating on its axis, but Charon would never move in the sky.
d. The observer would see different sides of Charon as it rotates on its axis and would see it rise and set as it orbits Pluto.

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?

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
