Oppositely charged parallel plates are separated by 5.78 millimeter. A potential difference of 600 Volt exists between the plates.
(a) Obtain the magnitude of electric field between plates?
in N/C
(b) Find the magnitude of the force on an electron between the plates?
in N
(c) Determine how much work must be done on the electron to move it to the negative plate if it is initially positioned 2.92 millimeter from the positive plate?
in J
