An electron initially at rest is released in a uniform electric field, the electron is accelerated horizontally to the right, traveling 4.77 m in the first 3.24x10-6s after being released, what is the magnitude of the electric field? electron q: 1.602x10-19 c m: 9.11x10-31 Ans in N/C kg.

A proton enters the uniform electric field produced by the two charged plates shown in the figure. The plate length is L = 11.5 cm. The magnitude of the electric field is 5.5 × 10ª N/C, and the speed of the proton when it enters is 1.3 × 10´ m/s. it + What distance d has the proton been deflected downward when it leaves the plates? Give you answer in units of mm.

The velocity of a particle (m = 10 mg, q = - 4.0 µC) at t = 0 is 20 m/s in the positive x-direction. If the particle moves in a uniform electric field of 20 N/C in the positive x- direction, what is the particle's velocity ( in m/s) at t = 8.4 s? Select one: O A. 53.60 O B. -47.20 O C. 36.80 D. -13.60 O E. 87.20
