$A$ plane electromagnetic wave of frequency $25\; GHz$ is propagating in vacuum along the $z$-direction. At a particular point in space and time,the magnetic field is given by $\overrightarrow{B} = 5 \times 10^{-8} \hat{j}\; T$. The corresponding electric field $\overrightarrow{E}$ is (speed of light $c = 3 \times 10^{8}\; m/s$):

• A
  $1.66 \times 10^{-16} \hat{i}\; V/m$
• B
  $15 \hat{i}\; V/m$
• C
  $-1.66 \times 10^{-16} \hat{i}\; V/m$
• D
  $-15 \hat{i}\; V/m$
