a uniform electric is produced by two parallel plates separeated by 3 cm and with a battery of 36 v across them
a. an electron and a proton are released from rest at in the middle between two plates, find the net forces (both magnitude and direction) exerteed on the electron and proton, respectively
b. find the speed of the electron and proton when they reach the charged plates
c. is thekinetic energy of the electron will be larger than that of the proton when they hit the plates?
