Question

E-Field Multiple Representations Figure 23-65a displays a grid with coordinates measured in meters. On the grid two charges are placed with their positions indicated as red circles. We call the charge at the position (1 m, 0 m) q_A, and the charge at the position (-1 m, 0 m) q_B. Figure 23-65b shows a set of possible vector directions. Below is a list of the components of possible E fields. For each of the following three cases: q_A = 0 q_B = 8 pi epsilon_0 E field at the point (x, y) = (-1 m, 1 m) II q_A = 0 q_B = -8 pi epsilon_0 E field at the point (x, y) = (-1 m, -1 m) III q_A = 16 p epsilon_0 q_B = -16 pi epsilon_0 E field at the point (x, y) = (0 m, -1 m) specify an arrow corresponding to the directions of the E field from figure (b) and a set of components from the list on the right. Each of your answers should consist of a capital letter and a small letter. a. Squareroot N/C)i b. (- Squareroot 8 N/C)j c. (-2 N/C)i d. (2 N/C) j e. (1/2 N/C)i + (1/2 N/C) i + 1/2 Squareroot 5 N/C)j f. (1/2 N/C)i - (Squareroot 5 N/C)j g. None of the above.

Explanation / Answer

I) Ad

II) Ad

III) Ga

note: i have assumed both charge having value 16. if first one is 160 instead of 16 and its not a mistake then for III) no direction will match and no option will match but we have option none of above for latter case.
