In the figure a uniform, upward electric field of magnitude 1.60 × 103 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 = 17.0 cm and separation d = 1.70 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 = 45.0° with the lower plate and has a magnitude of 6.40 x 105 m/s. (a) Will the electron strike one of the plates? (b) If so, which plate, top or bottom? (c) How far horizontally from the left edge will the electron strike? The L (a) (b) 7 (c) Number i Units >

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?

X Incorrect. In the figure particle 1 (of charge +1.76 mC), particle 2 (of charge +1.76 mC), and particle 3 (of charge Q) form an equilateral triangle of edge length a. For what value of Q (both sign and magnitude) does the net electric field produced by the particles at the center of the triangle vanish? Number i 1.76 Units C-m

A horizontal electron beam consists of electrons moving at 2000 m/s through two parallel, horizontal plates that are 0.01 m long and generate a uniform and constant 0.5 N/C electric field that points upward.  What is the vertical component of the electron's velocity upon exiting the field in m/s? Assume the plate separation is sufficient that you do not need to worry about the electrons hitting the plate.

An alpha particle (a helium nucleus) is traveling along the positive x-axis at 1200 m/s when it enters a cylindrical tube of radius 0.400 cm centered on the x-axis. Inside the tube is a uniform electric field of 5.50  10-4 N/C pointing in the negative y-direction. How far does the particle travel before hitting the tube wall? Neglect any gravitational forces. Note: m? = 6.64  10-27 kg; q? = 2e. m

A proton is projected horizontally midway between two parallel plates that are separated by 0.47 cm. The uniform electric field has magnitude 6.0 × 105 N/C between the plates. If the plates are 5.6 cm long, find the minimum speed of the proton if it just misses the lower plate as it emerges from the field. The gravitational force on the proton can be neglected.

Two horizontal parallel plates are separated by a distance of 174 mm creating an electric field of 23 μN/C directed north. An electron is place halfway between the two plates with and fired with initial velocity 58 m/s from the horizontal. Calculate the time it takes for the electron to land at the positive plate and its speed before hitting the plate. Provide an Illustration and answer in GRESA format.

A sphere is attached to a thread of length L = 21.7 cm and suspended from the ceiling, as shown in the figure. A uniform electric field points to the right in the figure. When  ? = 14.3°,  the sphere is in equilibrium. Find the net charge on the sphere (in µC).     What If? If the electric field is suddenly turned off, what is the speed of the sphere at the bottom of its swing (in m/s)?
