11. A long solenoid of radius R=5 cm has n=100 turns of wire per unit length and carries at time-dependent current that varies as I(t)=600 cos(4000 t). Recall that uo=4 n 10-7 T m/A. Find the expression for the induced electric field as a function of time, for example write is as E(t), at a point inside the solenoid at a distance r=1 cm from its central axis. Answer: a
