A horizontal straight wire $\displaystyle 5$ m long extending from east to west falling freely at right angle to horizontal component of earths magnetic field $\displaystyle 0.60 \times 10^{-4} \mathrm{Wbm}^{-2}$. The instantaneous value of emf induced in the wire when its velocity is $\displaystyle 10 \mathrm{~ms}^{-1}$ is $\displaystyle \_\_\_\_$ $\displaystyle \times 10^{-3} \mathrm{~V}$.
