In a plane electromagnetic wave travelling in free space, the electric field component oscillates sinusoidally at a frequency of \(2.0\times10^{10}\,\mathrm{Hz}\) and amplitude \(48\,\mathrm{V\,m^{-1}}\). Then the amplitude of oscillating magnetic field is : (Speed of light in free space \(= 3\times10^{8}\,\mathrm{m\,s^{-1}}\))
