NEET 2023 Physics question on Electromagnetic Waves

In a plane electromagnetic wave travelling in free space, the electric field component oscillates sinusoidally at a frequency of 2.0×10102.0 \times 10^{10} Hz and amplitude 48 V m−148\,\text{V m}^{-1}. Then the amplitude of oscillating magnetic field is (Speed of light in free space =3×108 m s−1= 3 \times 10^8\,\text{m s}^{-1})
