Two horizontal plates of opposite charge form a constant electric field = 1000 N/C directed vertically downwards. An electron of mass me and charge e* is fired horizontally with velocity v = 0.1c, where c = 3.00 x 108 m/s between the plates. Calculate the electron's acceleration. If the plates have length 1 m, find the electron's deflection from the horizontal when it emerges.

What must the charge (sign and magnitude) of a particle of mass 1.43 g be for it to remain stationary when placed in a downward-directed electric field of magnitude 660 N/C? Use 9.80 m/s2 for the magnitude of the free-fall acceleration.

In the figure a uniform, upward electric field of magnitude 1.70 x 10° N/C has been set up between two horizontal plates by charging the lower plate positively and the upper plate negatively. The plates have length L = 12.0 cm and separation d = 1.90 cm. An electron is then shot between the plates from the left edge of the lower plate. The initial velocity of the electron makes an angle e = 52.0° with the lower plate and has a magnitude of 6.60 x 106 m/s. (a) Will the electron strike one of the plates?

The electric field is zero everywhere except in the region 0≤x≤4.00 cm, where there is a uniform electric field of 110 N/C in the +y direction. A proton is moving in the +x direction with a speed of v = 1.00×10^6 m/s.

An electron is fired at 236,348m/s into a uniform electric field generated by two plates as shown. Determine the maximum magnitude of the electric field if the particle is to exit without hitting either of the plates. The electron enters the region at the midpoint directly between the plates. The length of the plates is 0.41m and the distance between the plates is 0.18m. (Your answer will be the positive magnitude of E in units of N/C, given to 3 decimal places of precision) e

A particle with charge q = +1e and mass m = 8.5 × 10-26 kg is injected horizontally with speed 2.5 × 106 m/s into the region between two parallel horizontal plates. The plates are 28 cm long and an unknown distance d apart. The particle is injected midway between the top and bottom plates. The top plate is negatively charged and the bottom plate is positively charged, so that there is an upward-directed electric field between the plates, of magnitude E = 38 kN/C. Ignore the weight of the particle. When the particle exits the region between the plates, what will be the magnitude of its vertical displacement from its entry height, in millimeters?
