A Long Solenoid (N = 1 500 Turns/m) Has a Cross-Sectional

A long solenoid (n = 1 500 turns/m) has a cross-sectional area of 0.40 m² and a current given by I = (4.0 + 3.0t²) A, where t is in seconds. A flat circular coil (N = 300 turns) with a cross-sectional area of 0.15 m² is inside and coaxial with the solenoid. What is the magnitude of the emf induced in the coil at t = 2.0 s?

A) 2.7 V
B) 1.0 V
C) 6.8 V
D) 0.68 V
E) 1.4 V
