In the figure above, an electron is released at an angle of 45 degrees from the parallel-plate capacitor's positive side. The distance between the plates is 2.50 cm and the electric field strength inside the capacitor is 3.50×104 N/C. If the electron avoids touching the negative plate, what is its maximum possible initial speed?

The figure below shows an electron entering a uniform electric field perpendicularly betweenthe middle of two plates with a velocity of 5.0 × 107 m s−1. Two flat parallel plates, each oflength 12.0 cm, are separated by a distance of 1.5 cm.The potential difference between the plates is 210 V.(a) Calculate the magnitude of the electric field strength between the plates.(b) Determine the magnitude and direction of the acceleration of the electron.(c) Calculate the time for the electron to travel a horizontal distance equal to the length of theplates.(d) Use your answers in (c) to determine whether the electron will hit one of the plates oremerge from between the plates.

An electron is accelerated from rest between two parallel plates that are seperated by 2.20 cm. The potential difference between the two plates is 2.10×103 V. If the electron travels from the negative plate to the positive plate, what will be the speed of the electron as it exits through a small hole in the positive plate? 2.72×107 m/s 2.20×107 m/s 3.24×107 m/s 4.03×106 m/s

A parallel plate capacitor is formed from two circular plates, each of radius 1.20 cm, separated by 1.70 mm. The plates are charged to ±±8.70 nC.A proton is shot from the negative plate to the positive. What launch speed must the proton have to just barely reach the positive plate?

An electron moves in the direction of a uniform electric field. Its initial speed is5.00 × 106 m s−1 and stops momentarily after moving through a distance of 20.0 cm.(a) What is the strength of the electric field?(b) Why the electron stops momentarily?

In an electron gun of a television set, an electron with an initial speed of 10^3 m/s enters a region where it is electrically accelerated. It emerges out of this region after 1 micro second with speed of 4 × 10^5 m/s. What is the maximum length of the electron gun.
