Problem 3-Accelerating an electron in the uniform electric field (20 points) The terminals of a 100 V battery are connected to two large, parallel, horizontal plates 2 cm apart. The resulting charges on the plates produce a nearly uniform electric field E = 5x10' N/ C in the region between the plates. Suppose the lower plate has positive charge. If an electron is released from rest at the upper plate, (a) what is its speed just before it hits the...
In the figure a uniform, upward electric field of magnitude 1.50 × 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 = 14.0 cm and separation d = 1.80 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 θ = 50.0° with the lower plate and...

An electron enters the lower left side of a parallel plate capacitor and exits at the upper right, as shown. The initial speed of the electron is 7"106 m/s. The capacitor is 2 cm long, the plates are 0.15 cm apart. Find the magnitude of the electric field between the plates, assuming that it is uniform everywhere. Problem 3 An electron enters the lower left side of a parallel plate capacitor and exits at the upper right, as shown. The...
A uniform electric field exists in a region between two oppositely charged parallel plates. An electron is released from rest at the surface of the negatively charged plate and strikes the surface of the opposite plate, 2 cm distant from the first, in a time interval of 1.5x10 s. (a) Find the electric field , (b) find the velocity of the electron when it strikes the second plate.
