Chapter 30, Problem 14P

GO In Fig. 30-42a, a uniform magnetic field $\stackrel{\to }{\text{B}}$ increases in magnitude with time t as given by Fig. 30-42b, where the vertical axis scale is set by B_s = 9.0 mT and the horizontal scale is set by t_s = 3.0 s. A circular conducting loop of area 8.0 × 10⁻⁴ m² lies in the field, in the plane of the page. The amount of charge q passing point A on the loop is given in Fig. 30-42c as a function of t, with the vertical axis scale set by q_s = 6.0 mC and the horizontal axis scale again set by t_s = 3.0 s. What is the loop’s resistance?
