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, 2.6 cm away, in a time 4.2 × 10-8 s. (a) What is the speed of the electron as it strikes the second plate? (b) What is the magnitude of the electric field?

Inside a cathode ray tube, an electron is in the presence of a uniform electric field with a magnitude of 275 N/C. (a) What is the magnitude of the acceleration of the electron (in m/s2)?                            m/s2 (b) The electron is initially at rest. What is its speed (in m/s) after 1.20 ✕ 10−8 s?                            m/s

An electron, initially at rest is placed in an electric field of 5?105 ?∕? directed west. What is the acceleration of the electron due to the electric field? Group of answer choices 4.79x10^13 m⁄s^2 4.79x10^-13 m⁄s^2 8.78x10^-16 m⁄s^2 8.78x10^16 m⁄s^2

At some instant the velocity components of an electron moving between two charged parallel plates are vx=1.6×105 m/s and vy-3.4x10³ m/s. Suppose the electric field between the plates is uniform and given by E what are (a) the electron's acceleration in that field and (b) the electron's velocity when its x coordinate has changed by 2.1 cm? 120N/C).
