Problem 1. Gauss and Graphs! A positively charged particle is held at the center of a spherical shell. This scenario is illustrated in Figure 1 where we see the magnitude, E, of the electric field versus radial distance r. The scale of the vertical axis is set by E, = 10.0 x 107 N/C, and the x-axis is given in centimeters (note 1 cm = 0.01 m, so you need to do that small conversion). (A) What is the charge of the particle? (B) What is the total charge of the shell? E, E (10' N/C) 0 2 3 r (cm) Figure 1: The accompanying figure to Problem 1 to illustrate the electric field as a function of radial distance. Note that I cm is equal to 0.01 m
