A uniform magnetic field exists in a region given by $\overrightarrow{\mathrm{B}}=3\hat{\mathrm{i}}+4\hat{\mathrm{j}}+5\hat{\mathrm{k}}\text{ T}$. A rod of length $5 \mathrm{m}$ is placed along the $y$-axis and it is moved along the $x$-axis with constant speed $1 \mathrm{m} {\mathrm{s}}^{-1}$. Then induced e.m.f. in the rod will be

• A

  zero
• Correct answer
  B

  $25 \mathrm{V}$
• C

  $20 \mathrm{V}$
• D

  $15 \mathrm{V}$

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