For a coil of 5 turns, the magnetic flux varies with time as $\phi_{B}(t) = (2t^3 - \frac{5}{2}t^2 + t)$, where $\phi_{B}(t)$ and t are in S.I. units. The induced current at $t=2s$ in the coil, if its total resistance is 150 Ω, is:

5.0 A 0.5 A 0.05 A 2.0 A

0.5 A

The correct answer is Option (2) → 0.5 A
