A Long Solenoid (Radius = 3

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
