a. An electron (mass me = 9.11 x 10-31kg, area charge q. = -e = -1.6 x 10-19C) is A released from rest at point 2. 2 What is the electric force experienced by the electron? 4 + Direction: + -Q +Q Magnitude: *=0 4 > * (mm ) b. Assume that the electric force is the only force acting on the electron (i.e. ignore air resistance and gravity). What is the velocity of the electron when it hits the positive plate (just before making contact)? c. What is the kinetic energy of the electron when it hits the positive plate (just before making contact)?The picture on the right shows a plate capacitor. You may assume that the two plates are very area large compared to the separation between the + A plates (i.e. you may treat them as 'infinite' planes). O The plates are charged to 1Q, each plate has an - area of A, and the plates are separated by a distance d. The x-axis in this problem is pointing from the negative to the positive plate, with the Q +Q - origin at the negative plate. The electric field at 4 6 -> x (mm) X=0 12 point 2 has a magnitude of E. E = 3000 A = 1m2 d = 8 mm Co = 8.85 x 10-12 C2 Nm2
