- The electric field between two parallel plates is uniform, with magnitude 704 N/C. A proton is held stationary at the positive plate, and an electron is held stationary at the negative plate. The plate separation is 4.06 cm. At the same moment, both particles are released. Question: Calculate the distance (in cm) from the positive plate at which the two pass each other. Ignore the electrical attraction between the proton and electron.A proton is projected through a perpendicular uniform electric field as shown. The region of the electric field is 12cm long as shown. The distance between the upper and lower plates is 6.78mm. The proton starts at the vertical midpoint with an initial horizontal speed of 8.29 ×10*m/s. Determine the magnitude of the maximum electric field for which the proton can make it through without hitting the lower plate (in N/C).In a hydrogen atom in its ground state, the electron is on average a distance of about 0.5 x 10-10 m from the proton. What is the magnitude of the electric field due to the proton at this distance from the proton?
- In a CRT, after the electrons pass through the anode, they are moving in the z-direction at a speed of 8.40 x 10° m/s. They then pass between a pair of vertical parallel plates (A) and then between a pair of horizontal parallel plates (B). All four of these plates are squares 2.50 cm on a side. The plates of each pair are separated by 1.50 cm.The electric field between plates (A) is zero. As the beam exits the space between plates (B), it has been deflected 2.00 mm downward (Ay = -2.00 mm). In what direction is the beam moving now? Enter a positive value if the angle is below the horizontal and enter a negative value if the angle is above the horizontal.

- A sphere of uniform charge density rho=10^−6 C/m 3 has a small hole drilled along its diameter, forming a tunnel from one end of the sphere to the other. An electron is released at the opening of the tunnel and begins to move, speeding up towards the center of sphere. After it passes the center of the sphere, it begins to slow down until it reaches the other end of the tunnel and stops. The electron then moves back up to the first opening and start the cycle again. It repeats this cycle many times. Find the frequency of this cyclic motion.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) eA 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?
