If the magnetic field in a plane electromagnetic wave is given by B = 3 × 10⁻⁸ sin(1.6 × 10³x + 48 × 10¹⁰t) j T, then what will be expression for electric field ?

(A) E = (9sin(1.6 × 10³x + 48 × 10¹⁰t) k V/m)

(B) E = (60sin(1.6 × 10³x + 48 × 10¹⁰t) k V/m)

(C) E = (3 × 10⁻⁸ sin(1.6 × 10³x + 48 × 10¹⁰t) i V/m)

(D) E = (3 × 10⁻⁸ sin(1.6 × 10³x + 48 × 10¹⁰t) j V/m)
