Concept explainers
Predict/Calculate Referring to Example 19-14 Suppose q1 = +2.90μC is no longer at the origin, but is now on the y axis between y = 0 and y = 0.500 m. The charge q2 = +2.90μC is at x = 0 and y = 0.500 m, and point 3 is at x = y = 0.500 m. (a) Is the magnitude of the net electric field at point 3, which we call Enet, greater than, less than, or equal to its previous value? Explain. (b) Is the angle θ that Enet makes with the x axis greater than, less than, or equal to its previous value? Explain. Find the new values of (c)Enet and (d) θ if q1 is at y = 0.250 m.

- Show that the maximum magnitude Emax of the electric field along the axis of a uniformly charged ring occurs at x=a/2 (see Fig. 23.3) and has the value Q/(630a2).

The inventor devised a system that allows an 85.0-kg human to hover above the ground at the surface of the Earth due to the repulsive force between a charge q applied to his body and the normal electric charge on the Earth. The normal charge on the Earth is such that the electric field is uniform from near the Earths surface, directed downward toward the surface, and is of magnitude 130 N/C at the location of the engineers experiments. Everything went well until the engineer tried a new experiment. He attempted to transfer the same amount of charge q to each of two experimental subjects standing next to each other, so they could hover and work close together on a task. The charged, hovering experimental subjects repelled each other and were injured as they flew away in opposite directions. Both experimental subjects are now suing the inventor for their injuries. The inventor is claiming that it is not his fault if the subjects find each other repulsive. To find out whether the inventor has a good defense, determine the initial acceleration of each subject if they are working 1.00 m apart.arrow_forwarda point charge of magnitude 5.00 C is at the origin of a coordinate system, and a charge of 4.00 C is at the point x = 1.00 m.

(c) Show by conceptual arguments that the point must be between x = 1.00 m and x = positive infinity.
