Question.4759 - Pre-Lab QuestionsA circular ring with a radius of 0.5 m lies horizontally on a surface (Figure 4). A uniform electric field of magnitude 1000 N/C is angled 40 ° from the horizontal. Calculate the flux through the ring.Figure 4: A ring in an electric field (arrows).A single positive charge is enclosed in a square box. How will the flux change if the charge is enclosed within a cylinder (Figure 5)?Figure 5: A single positive charge enclosed in a square box and cylinder.Formulate an equation to determine the flux through the right face of the square (Figure 6). Record your answer in variable form.Figure 6: Pre-Lab Question 3 reference.Determine which of the following cubes (Figure 7) encloses a positive, negative, and zero net charge. Explain your answer. The number next to the arrow represents the magnitude of the electric field.Figure 7: Various cubes in electric fields.For a single, positive point charge, show that the flux through the surface of a sphere is equal to: In Faraday’s ice pail experiment, a charged object is first suspended inside of the ice pail (Figure 8). The object is then set on the bottom of the pail (Figure 8), giving it a net charge. Draw a diagram showing the charge distribution on the ice pail when the ball is suspended and after the charged ball touches the bottom. Include an explanation of your diagrams.Figure 8: A charged object suspended in Faraday’s ice pail (left).

Use you results to support your answer.Did the pith ball react when the white rod was located above the Styrofoam cup? Did the pith ball react when the can was brought near it? Explain why or why not.How did the pith ball interact when the white rod was placed inside the can? Explain your observation.Explain the interaction between the white rod and pith ball after it touched the side of the can.What does touching the inner surface of the can do to cause the observation you made in Table 2?How do your final two observations of the pith ball inside the charged container support Gauss’s Law?
