Unformatted text preview: V max = 40 V. (c) In view of our result in part (b), we see that now (to ±nd V = 0) we are looking for some X > 3 m such that the “area” from x = 3 m to x = X is 40 V. Using the formula for a triangle (3 < x < 4) and a rectangle (4 < x < X ), we require 1 2 (1)(20) + ( X − 4)(20) = 40 . Therefore, X = 5 . 5 m....
