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

• A
  $1.8 \times 10^{-4} \text{ V}$
• B
  $1.3 \times 10^{-4} \text{ V}$
• C
  $1.2 \times 10^{-4} \text{ V}$
• D
  $4.8 \times 10^{-4} \text{ V}$
