A parallel plate capacitor consists of two rectangular, horizontally oriented plates, each with an area of 4.00 cm2, and separated by a distance of 0.300 mm. If the magnitude of the charge on each capacitor is 5.00 nC, what is the magnitude of the electric field at a height of 0.800 cm between both plates?

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.

In this example, we will analyze the motion of an electron that is released in an electric field. The terminals of a 100 V battery are connected to two large, parallel, horizontal plates 1.0 cm apart. The resulting charges on the plates produce an electric field E in the region between the plates that is very nearly uniform and has magnitude E = 3.0×104 N/C. Suppose the lower plate has positive charge, so that the electric field is vertically upward, as shown in (Figure 1). (The thin pink arrows represent the electric field.) If an electron is released from rest at the upper plate, what is its speed just before it reaches the lower plate? How much time is required for it to reach the lower plate? The mass of an electron is mẹ = 9.11 x 10-31 kg. The thin arrows represent the uniform electric field. 1.0 cm 100 V In this example, suppose a proton (mp = 1.67 × 10-27 kg) is released from rest at the positive plate. What is its speed just before it reaches the negative plate? Express your…

In a typical television or in an older computer picture tube (CRT), the electrons that strike the screen to form an image are accelerated between two charged plates that have a potential difference of 2.5×104 V. The plates are separated by a distance of 1.3 cm. Assuming that there is a uniform electric field between the plates, calculate the strength of the field.

A uniform electric field exists in the region between two oppositely charged plane parallel plates. A proton is released from rest at the surface of the positively charged plate and strikes the surface of the opposite plate, 1.60 cm distant from the first, in a time interval of 1.50 × 10-6 s. a. Find the magnitude of the electric field. b. Find the speed of the proton when it strikes the negatively charged plate. Hint: Use both kinematics and electric field equations in solving the problem

The figure shows two parallel plates that are 2.0 cm apart. The electric field between them is 3.4 × 104 N/C. An electron is launched at a 45° angle and with initial speed v, from the positive plate. What is the maximum V, such that the electron won't hit the negative plate? 2.0 cm 45°

A small plastic ball with a mass of 6.5 x 10-3 kg and with a charge of +0.15 uC is suspended from insulating thread and hangs between the plates of capacitor. The ball is in equilibrium with the thread making an angle of 30 degrees with respect to vertical. The ball is displaced by 0.15 m from its vertical position. What is the magnitude of the electric field between the two plates?
