Question

In Figure 18.32 in the 9th edition or 18.31 in the 10th edition, a positive charge is surrounded by a sphere of radius r Imagine that the sphere is expanded to a radius of 2r. What would the effect on the flux be? The flux would be twice as great The flux would be unchanged The flux would be half as much The flux would be one-fourth as much. UESTION 4 Consider Example 8 (p. 541 in the 9th edition or 493 in the 10th edition). Suppose you had a similar configuration in which the vector EB had the exact same magnitude and direction, and the vector EA had the exact same direction but a slightly different magnitude. Suppose you also knew that 8 had a value of 30° instead of the value in the example. What would you conclude the magnitude of vector EA would have to be? 5.2 N/C O N/C 3.5 N/C It's impossible to say
