A plane electromagnetic wave propagating in $\displaystyle x$-direction is described by $\displaystyle \mathrm{E}_y=\left(200 \mathrm{Vm}^{-1}\right) \sin \left[1.5 \times 10^7 \mathrm{t}-0.05 x\right]$; The intensity of the wave is : (Use $\displaystyle \epsilon_0=8.85 \times 10^{-12} \mathrm{C}^2 \mathrm{~N}^{-1} \mathrm{~m}^{-2}$ )
