The electric field in a plane electromagnetic wave is given by : E_y=69 \sin [0.6 \times 10^3 x-1.8 \times 10^{11} t] V \/ m. [21 Jan 2026 Shift 1]

Correct Answer is : Bz=2.3×10−7sin[0.6×103x−1.8×1011t]

B_z=2.3 \times 10^{-7} \sin [0.6 \times 10^3 x-1.8 \times 10^{11} t]

B_z=2.3 \times 10^{-7} \sin [0.6 \times 10^3 x+1.8 \times 10^{11} t]

B_y=2.3 \times 10^{-7} \sin [0.6 \times 10^3 x-1.8 \times 10^{11} t]

B_y=69 \sin [0.6 \times 10^3 x+1.8 \times 10^{11} t]
