Recalculate a) the particle position (x, y) and b) Vyr at time t= 2.4 X 10'8 s using the necessary values he has calculated, c) use mass of electron (9. 11 x 10-31 kg) to calculate the kinetic energy of the particle based on the velocity magnitude of at the given time. An electron enters the region of a uniform electric field as shown in the figure, with v; = 3.00 x 106 m/s and E = 200 N/C. The horizontal length of the plates is . = 0.100 m.
