Physics 222 Homework #2 on Chapter 22 of text Choose the best answer from each question. Use the following to answer questions 1-3. p Q, L L Figure 1: A continuous uniform charge distribution in the shape of a straight line segment (length = L, total charge = Q) is shown in Figure 1. A field point p is defined to be along the axis of the charge the same distance L from the closest end of the charge. 1. Assume for this problem only that the field point p is moved so that it is a distance 2L from the closest end of the charge distribution. The electric field at this new point p has a magnitude closest to _________. A) kQ 4 L 2 B) kQ 3 L 2 C) kQ 6 L 2 D) kQ 2 L 2 E) kQ L 2 2. The electric field at point p has a magnitude closest to _________. A) kQ L 2 B) kQ 2 L 2 C) kQ 3 L 2 D) kQ 6 L 2 E) kQ 4 L 2 3. Assume for this problem only that the charge distribution is stretched horizontally toward the left so that it has a new length of 2L and the same charge Q. The electric field at point p a distance L away has a
