The magnetic field of a plane electromagnetic wave is given by : $$\overrightarrow{\mathrm{B}}=\mathrm{B}_0 \hat{i}[\cos (\mathrm{kz}-\omega \mathrm{t})]+\mathrm{B}_1 \hat{j} \cos (\mathrm{kz}+\omega \mathrm{t}) $$ where $\displaystyle \mathrm{B}_0=3 \times 10^{-5} \mathrm{~T}$ and $\displaystyle \mathrm{B}_1=2 \times 10^{-6} \mathrm{~T}$. The rms value of the force experienced by a stationary charge $\displaystyle \mathrm{Q}=10^{-4} \mathrm{C}$ at $\displaystyle \mathrm{z}=0$ is closest to :
