A plane electromagnetic wave of frequency 500 MHz is travelling in vacuum along y – direction. At a particular point in space and time, $\vec{B} = 8.0 \times 10^{- 8} \hat{z} T$ . The value of electric field at this point is:
(Speed of light $= 3 \times 10^{8} m s^{- 1}$ )
$\hat{x}, \hat{y}, \hat{z}$ are unit vectors along x, y and z directions.
