The magnetic field of a plane electromagnetic wave is given by $\overrightarrow{\mathrm{B}}={\mathrm{B}}_0\widehat{\mathrm{i}}\left[\mathrm{c}\mathrm{o}\mathrm{s}\left(\mathrm{k}\mathrm{z}-\mathrm{\omega }\mathrm{t}\right)\right]+{\mathrm{B}}_1\widehat{\mathrm{j}}\mathrm{c}\mathrm{o}\mathrm{s}\left(\mathrm{k}\mathrm{z}+\mathrm{\omega }\mathrm{t}\right)$, where ${\mathrm{B}}_0=3\times {10}^{–5}\mathrm{ }\mathrm{T}$ and ${\mathrm{B}}_1=2\times {10}^{–6}\mathrm{ }\mathrm{T}$. The RMS value of the force experienced by a stationary charge $\mathrm{Q}={10}^{–4}\mathrm{ }\mathrm{C}$ at $\mathrm{z}=0$ is closest to

• A

  $0.1\mathrm{ }\mathrm{N}$
• B

  $0.9\mathrm{ }\mathrm{N}$
• C

  $3\times {10}^{–2}\mathrm{ }\mathrm{N}$
• Correct answer
  D

  $0.6\mathrm{ }\mathrm{N}$

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