In a plane electromagnetic wave travelling in free space, the electric field component oscillates sinusoidally at a frequency of 2.0 \times 10^{10} {\Hz} and amplitude 48 {\V} {\m}^{-1}. Then the amplitude of oscillating magnetic field is (Speed of light in free space =3 \times 10^8 {\m} { s}^{-1} ) [NEET 2023]

Correct Answer is : 1.6×10−7T
