In a plane electromagnetic wave travelling in free space, the electric field component oscillates sinusoidally at a frequency of \( 2.0 \times 10^{10}\text{ Hz} \) and amplitude \( 48\text{ V m}^{-1} \). Then the amplitude of oscillating magnetic field is : (Speed of light in free space \( = 3 \times 10^8\text{ m s}^{-1} \))
