일반물리학 2 — Gauss' Law: Problem 6

6 Figure 23-23 gives the magnitude of the electric field inside and outside a sphere with a positive charge distributed uniformly throughout its volume. The scale of the vertical axis is set by \(E_s = 10 \times 10^7 \text{ N/C}\). (a) What is the charge on the sphere? (b) What is the field magnitude at \(r = 8.0 \text{ cm}\)?
