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

  2. I see two crrect statements.

    The electric field between the plates is actually 50V/0.01 m = 5000 V/m

    A proton released from the positive plate will strike the negative plate with 50 eV of energy
