*27 ILW In Fig. 32-34, a uniform electric field E collapses. The verti- cal axis scale is set by E, = 6.0 x 10 N/C, and the horizontal axis scale is set by t, = 12.0 µs. Calculate the magnitude of the displacement cur- rent through a 1.6 m2 area perpen- dicular to the field during each of the time intervals a, b, and c shown on the graph. (Ignore the behavior at the ends of the intervals.) E, Time (us) Figure 32-34 Problem 27. E (10 N/C)

У (ст) 91 A point charge g, = -4 µC is placed at x = 0 and y = +5 cm. A second point charge g, = -4.5 µC is placed at x = +5 cm and y = 0. Determine the magnitude of the net electric field at the origin and the direction of the electric field as an angle measured from the +x axis.

The figure shows a coaxial cable in Cross-Section. The two conductors have inner and outter radii as shown and carry oslo linear charge densities winner = -14.4 nC/m 12h and nouter 20.5 nc/m. Given rA = 12 cm, r = 13.3cm, rc = 20.5 cm, and rp = 23.3 cm, determine the magnitude of the electric field at a point 47cm from the central axis.
