Two parallel plates, separated by 10 mm, are charged to a potential difference of 50 V (that is, one plate is 0 V and the other plate is 50 V). Which of the following statements are true?
the electric potential at the midpoint between the plates is 50 V
the electric field between the plates is 5000 V/m
a proton released from the positive plate will strike the negative plate with 50 eV of energy
an electron placed midway between the plates will be pulled towards the negative plate
the electric field between the plates is 500 V/m
