A conducting circular loop of radius $\displaystyle \frac{10}{\sqrt{\pi}} \mathrm{~cm}$ is placed perpendicular to a uniform magnetic field of $\displaystyle 0.5$ T. The magnetic field is decreased to zero in $\displaystyle 0.5$ s at a steady rate. The induced emf in the circular loop at $\displaystyle 0.25$ s is:
