(selectall that apply.)
a. each particle is acted upon by the sameelectric force and has the same acceleration.
b. the magnitude of the acceleration of theelectron is greater than that of the proton.
c. the electric force on the proton isgreater in magnitude than the electric force on the electron, butin the opposite direction.
d. both particles have the same acceleration.
e. the electric force on the proton is equalin magnitude to the electric force on the electron, but in the opposite direction.

As you are trying to move a heavy box of mass m, you realize that it is too heavy for you to lift by yourself. there is no one around to , so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley. you pull up on the rope to lift the box. use g for the magnitude of the acceleration due to gravity and neglect friction forces. once you have pulled hard enough to start the box moving upward, what is the magnitude f of the upward force you must apply to the rope to start raising the box with constant velocity? express the magnitude of the force in terms of m, the mass of the box.
