a. The Figure shows the cross section of a solid cylindrical conductor with radius R. The conductor is carrying a uniformly distributed current I (out of page). Find the magnitude of the magnetic field, B, inside the conductor a distance r= R/4 from the center. Figure 2: Question 3(a) b. Indicate the direction of the electric field between the plates of the parallel plate capacitor shown in the drawing if the magnetic field is decreasing in time. Give your reasoning. B (out of paper) Capacitor
