A square loop of side 10 cm and resistance 0.5 $\Omega$ is placed vertically in the east-west plane. A uniform magnetic field of 0.10 T is set up across the plane in the north-east direction. The magnetic field is decreased to zero in 0.70 s at a steady rate. Determine the magnitudes of induced emf $\varepsilon$ and current $I$ during this time-interval.

Question

(A) $\varepsilon = 1.0mV$ and $I = 2mA$ (B) $\varepsilon = 2.0mV$ and $I = 1mA$ (C) $\varepsilon = 1.2mV$ and $I = 2.1mA$ (D) $\varepsilon = 1.0mV$ and $I = 2.1mA$
