A Long Solenoid (Radius = 3

Multiple Choice

A long solenoid (radius = 3.0 cm, 2 500 turns per meter) carries a current given by I = 0.30 sin(200πt) A, where t is measured in s. When t = 5.0 ms, what is the magnitude of the induced electric field at a point which is 2.0 cm from the axis of the solenoid?

A) 7.3 × 10−³ V/m
B) 6.4 × 10−³ V/m
C) 6.9 × 10−³ V/m
D) 5.9 × 10−³ V/m
E) 8.9 × 10−³ V/m
