A long solenoid (radius = 3.0 cm, 2 500 turns per meter) carries a current given by I = 0.30 sin(200 t) A, where t is measured in s. When t = 2.5 ms, what is the magnitude of the induced electric field at a point which is 4.0 cm from the axis of the solenoid?
a. 9.3 10-3 V/m
b. 8.0 10-3 V/m
c. 6.7 10-3 V/m
d. 5.3 10-3 V/m
e. 1.9 10-3 V/m
