If the magnetic field of a plane electromagnetic wave is given by (The speed of light = 3 × 10 8 m / s ) B = 100 × 10 - 6 sin ⁡ 2 π × 2 × 10 15 t - x c then the maximum electric field associated with it is:

Question

If the magnetic field of a plane electromagnetic wave is given by (The speed of light = 3 × 10 8 m / s ) B = 100 × 10 - 6 sin ⁡ 2 π × 2 × 10 15 t - x c then the maximum electric field associated with it is:, 3 × 10 4 N C - 1, 4 × 10 4 N C - 1, 4.5 × 10 4 N C - 1, 6 × 10 4 N C - 1

We know that relation between electric field E and magnetic field B is given by: E B = c ⇒ E = B c = 100 × 10 - 6 × 3 × 10 8 V m - 1 = 3 × 10 4 V m - 1
