The electric field in a plane electromagnetic wave is given by E_z=60 \cos (5 x+1.5 \times 10^9 t) {\V} \/ {\m} Then expression for the corresponding magnetic field is (here subscripts denote the direction of the field) : [NEET 2025]

Correct Answer is : By=2×10−7cos(5x+1.5×109t)T

B z=60 \cos (5 x+1.5 \times 10^9 t) T

B_y=60 \sin (5 x+1.5 \times 10^9 t) T

B_y=2 \times 10^{-7} \cos (5 x+1.5 \times 10^9 t) T

B_x=2 \times 10^{-7} \cos (5 x+1.5 \times 10^9 t) T
