An object with a 5.0 C charge is accelerating at 0.0050 m/s2 due to an electric field. If the object has a mass of 2.0 mg, what is the magnitude of the electric field in N/C?

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…

An electron is moving horizontally at 3 x 10^6 m/s when it enters an electric field. If the electron deflects 0.9 cm downward in a distance of 2.5 cm determine the magnitude and direction of the electric field.

A ball with charge (1.200x10^1) µC hangs from a string in a horizontal electric field E=(1.47x10^2) N/C. If the string hangs at an angle θ=(3.3000x10^1)°, what is mass of the ball?  Give your answer in grams to 3 sf.

Inside a cathode ray tube, an electron is in the presence of a uniform electric field with a magnitude of 275 N/C. (a) What is the magnitude of the acceleration of the electron (in m/s2)?                            m/s2 (b) The electron is initially at rest. What is its speed (in m/s) after 1.20 ✕ 10−8 s?                            m/s

In an experiment similar to the setup described in the Example, a positively charged particle of mass m is released from rest at the surface of the positive plate. The velocity of the particle at the negative plate is 1.30 ✕ 105 m/s. If the electric field magnitude is 6.00 ✕ 103 N/C, the distance between the two plates is 5 cm, and the charge on the particle is 3e, what is the particle's mass (in kg)?

A proton is initially at rest. After some time, a uniform electric field is turned on and the proton accelerates. The magnitude of the electric field is 1.46  105 N/C.  What is the speed of the proton after it has traveled 7.00 cm?  What is the speed of the proton after it has traveled 70.0 cm?

At some instant the velocity components of an electron moving between two charged parallel plates are vx=1.6×105 m/s and vy-3.4x10³ m/s. Suppose the electric field between the plates is uniform and given by E what are (a) the electron's acceleration in that field and (b) the electron's velocity when its x coordinate has changed by 2.1 cm? 120N/C).

A particle (mass =67x 10 kg charge = +3.2 x 10" C) moves along the positive x axis with a speed of 4.8x 10 m/s. It enters a region of uniform electric field parallel to its motion and comes to rest after moving 20 m into the field. What is the magnitude of the electric field?
