After a distance of 1.35 m the proton reaches a speed of 1.97 x 105 m/s (m, = 1.67 x 10-27 kg, q,= 1.60 x 10-19 C). a) What is the final kinetic energy of the proton? b) What is the potential energy difference of the proton? c) What is the magnitude of the electric field?

Suppose you have two parallel conducting plates that are separated by 2.2 mm. a. What will the electric field strength between the plates be (in N/C) if they have a potential difference of 4.6 × 103 V? E = b. The electric breakdown strength for a particular medium, also called the dielectric strength, is the point at which electrons bound to the molecules of the medium begin to be stripped off due to the large electric field. How close together must the plates be with this applied voltage in order to achieve breakdown strength for air (3.0 × 106 V/m) in mm?  dbreakdown=

k3 8.99 x 10° Nm?/C?, me 3D 9.11 x 10-31 kg, e %3D 1.6 х 10-19 С, тр 3D 1.67 х 10-27 kg 1. Electrons start from rest and are accelerated east by two plates (parallel to the north/south directions) through a potential difference. They then pass into a second set of parallel plates 1.2 cm long (parallel to the east/west direction). When the electrons leave the second set of plates they are moving at 3.0 x 106 m/s [E 30º N]. You may ignore gravity. (For this question but not in the real world!) Find the potential difference across the first set of plates and the electric field between the second set of plates. 1.2 cm Path of electron First set of plates Second set of plates

Two large aluminum plates are separated by a distance of 2.0 cm and are held at a potential difference of 195 V. An electron enters the region between them at a speed of 3.2 × 105 m/s by passing through a small hole in the negative plate and continues moving toward the positive plate. Assume the electric field between the plates is uniform. 1. What is the electron’s speed, in meters per second, when it is 0.1 cm from the negative plate?  2. What is the electron’s speed, in meters per second, when it is 0.5 cm from the negative plate?  3. What is the electron’s speed, in meters per second, when it is 1.0 cm from the negative plate?  4.
