The electric field in an electromagnetic wave is given
\( E = (50 \, \text{N C}^{-1}) \sin \omega (t - x / c) \)
The energy contained in a cylinder of volume \( V \) is \( 5.5 \times 10^{-12} \, \text{J} \), The value of \( V \) is ________ \( \text{cm}^{3} \).
(given \( \varepsilon_{0} = 8.8 \times 10^{-12} \, \text{C}^{2} \text{N}^{-1} \text{m}^{-2} \))
