An electron with an initial speed v =3.1 x 106 mls is shot into a parallel plate capacitor at a 45 angle as shown in the diagram. The plates are separated by a distance d = 2.4 cm. charge on electron = -1.60 x 10- 19 C mass of electron = 9.11 x 10-31 kg (a) What is the minimum magnitude of electric field required to prevent the electrons from hitting the top plate?

(b) Between the capacitor plates, which direction do the electric field lines point? Circle your answer; no need to explain.

PART 1. Two problems. Show work clearly. Partial credit is allowed. Be sure to give answers with correct units. Problem 1. 10 pts. An electron with an initial speed v = 3.1 x 10'5 m/s is shot into a parallel plate capacitor at a 45 angle as shown in the diagram. The plates are separated by a distance d = 2.4 cm. charge on electron = -l .60 x 10'19 C mass of electron = 9.11 x 10\"31 kg (a) What is the minimum magnitude of electric eld required to prevent the electrons from hitting the top plate? (b) Between the capacitor plates, which direction do the electric eld lines point? Circle your answer; no need to explain. Upward Downward
