A uniform electric field is shown below. Draw equipotential surfaces. In which direction does the voltage decrease? If an electron is placed in the electric field at rest, draw the direction of the force. The electron moves from higher potential point to lower potential point or the other way around? If the potential difference between two locations of the electron is 5V, what is the change in potential energy of the electron. What is its speed at the end of...
1- For a uniform electric field, how is the electric potential energy similar to the gravitational potential energy in a uniform gravitational? 2-If a positive charge and a negative charge moving the same way in an electric field have the same change in electric potential energy? 3-For a positive charge moving in an electric field, which direction of motion will cause the electric potential energy to increase? Decrease? Stay constant? 4-How would the answers to the previous question be different...
1. Describe a uniform electric field. 2. Explain a practical method to create a uniform electric field. 3. In the electrode configuration of Figure 3-a, notice that the equipotential lines are circles which are closer to each other near the point terminal. Explain. (Hint: refer to the relation of the electric field around a point charge, and the relation where DV is the difference in potential between any two points, and r is the distance between them.) 4. In principle,...

A particle of a mass 1.2 x 10 ^-11 kg and a negative charge -1.0 uC moves to the right with a speed of 3.0 x 10 ^3 m/s. It enters a uniform electric field region where the field is known to be parallel to particle's direction of motion. If the particle is to be brought to rest in the space of 4.0cm what potential difference does it have to through to stop this way and what is the strength...

Problem 1a: Velocity Selector: Show that with the right ratio of electric to magnetic field strength a particle of velocity v will proceed through both fields in a straight line at constant speed (hint: you will need an equation containing v. Also: what does the straight line at constant speed give you?). Assume that the angle of the velocity vector relative to the magnetic field vector is 90 degrees.

A uniform electric field has magnitude E and is directed in the negative i direction. The potential difference between point a (at x= 0.65 m) and point b (at x = 0.90 m) is 260 V.Calculate the value of E. Part C A negative point charge q= -0.200 pC is moved from b to a. Calculate the work done on the point charge by the electric field.
