The amplitude of the magnetic field in a plane electromagnetic wave is given by:$$B = \frac{E}{c}$$where:* B is the amplitude of the magnetic field in teslas (T)* E is the amplitude of the electric field in volts per meter (V/m)* c is the speed of light in meters per second (m/s)In this problem, the amplitude of the electric field is 100 V/m. The speed of light is 3 x 10^8 m/s. Therefore, the amplitude of the magnetic field is:$$B = \frac{100 V/m}{3 x 10^8 m/s} = 3.3 x 10^{-7} T$$Therefore, the correct answer is A.
