a) Two parallel plates are separated by 2.0 cm and have apotential difference between them of 30 V. The mass of an electronis 9.1 x 10^-31kg and the charge of an electron is 1.6 x 10^-19 C.The electron field between the plates is constant in magnitude anddirection. What is the magnitude of the electric field between theplates?
b) The capacitance of the parallel plates is 3.7 μF. What is themagnitude of the charge on each plate?
c) If an electron is initially at rest on the negatively chargedplate, and is allowed to accelerate toward the positive plate, whatis the speed of the electron just before it hits the positiveplate?
