A rectangular wire loop of sides $5 \mathrm{~cm}$ and $3 \mathrm{~cm}$ with a small cut is moving away from an infinitely long straight wire carrying a current of $30 \mathrm{~A}$ with a velocity of $20 \mathrm{~ms}^{-1}$ as shown in the figure. The emf induced across the cut is

• A

  $50 \mu \mathrm{V}$
• B

  $75 \mu \mathrm{V}$
• Correct answer
  C

  $180 \mu \mathrm{V}$
• D

  $150 \mu \mathrm{V}$

Hence, the correct answer is option: 'C'.
