Concept explainers
Consider the electric field at the three points indicated by the letters A, B, and C in Fig. 16—49. First draw an arrow at each point indicating the direction of the net force that a positive test charge would experience if placed at that point, then list the letters in order of decreasing field strength (strongest first). Explain.
The direction of net force experienced by a positive test charge at each point in the given figure.
Answer to Problem 19Q
Solution:
The direction of net force at the given points is drawn.
Decreasing order of field strength is A > B > C
Explanation of Solution
The direction of net forces is drawn at the points A, B & C. At the point C the net force is zero.
The order of letters in decreasing order of field strength is given by, A > B > C
