Question

Halliday, Fundamentals of Physics, 10e nt GENERAL PHYSICS CAL BASED (PHYS 150/151) nt Chapter 22, Problem 055 Your answer is partially correct. Try again. A uniform electric field exists in a region between two oppositely charged plates. An electron is released from rest at the surface of the negatively charged plate and strikes the surface of the opposite plate, 2.9 cm away, in a time 8.5 (a) N (b) Number 145.67 x 108 s. (a) What is the speed of the electron as it strikes the second plate? (b) what is the magnitude of the electric feld? 6.8e6 Question Attempts: 2 of 10 used

Explanation / Answer

d = v0 t + a t^2 / 2

0.029 = 0 + a(8.5 x 10^-8)^2 / 2

a = 8.028 x 10^12 m/s^2

(A) v = v0 + at = 6.82 x 10^5 m/s

(B) a = q E / m

8.028 x 10^12 = (1.6 x10^-19) E / (9.109 x 10^-31)

E = 45.7 V/m
