A rectangular wire loop of sides $\displaystyle 8$ cm and $\displaystyle 3$ cm with a small cut, is moving out of a region of uniform magnetic field of magnitude $\displaystyle 0.3$ T directed normal to the plane of the loop. The emf developed across the cut, if the velocity of the loop is $\displaystyle 2 \mathrm{~cm} \mathrm{~s}^{-1}$, in a direction normal to the shorter side of the loop, will be :
