A metal loop of area $10{\text{cm}}^2$ is placed in a region such that its area vector points along $k$. The region contains a uniform magnetic field of magnitude $1.73T$ that points in the direction $i+j+k$. When the magnetic field is switched off, the field decreases to zero at a steady rate in $10s$, then the magnitude of emf induced in the loop is
