Q13. The magnetic field in a plane electromagnetic wave is $\mathrm { B } _ { \mathrm { y } } = \left( 3.5 \times 10 ^ { - 7 } \right) \sin \left( 1.5 \times 10 ^ { 3 } x + 0.5 \times 10 ^ { 11 } t \right) \mathrm { T }$. The corresponding electric field will be :\\
(1) $E _ { y } = 10.5 \sin \left( 1.5 \times 10 ^ { 3 } x + 0.5 \times 10 ^ { 11 } t \right) \mathrm { Vm } ^ { - 1 }$\\
(2) $E _ { z } = 1.17 \sin \left( 1.5 \times 10 ^ { 3 } x + 0.5 \times 10 ^ { 11 } t \right) \mathrm { Vm } ^ { - 1 }$\\
(3) $E _ { y } = 1.17 \sin \left( 1.5 \times 10 ^ { 3 } x + 0.5 \times 10 ^ { 11 } t \right) \mathrm { Vm } ^ { - 1 }$\\
(4) $E _ { z } = 105 \sin \left( 1.5 \times 10 ^ { 3 } x + 0.5 \times 10 ^ { 11 } t \right) \mathrm { Vm } ^ { - 1 }$
