At a particular point in space and time, the magnetic field is given by $\overrightarrow B = 5 \times {10^{ - 8}}\widehat jT$. The corresponding electric field $\overrightarrow E $ is (speed of light c = 3 × 108 ms–1)

Question

A plane electromagnetic wave of frequency 25 GHz is propagating in vacuum along the z-direction. At a particular point in space and time, the magnetic field is given by $\overrightarrow B = 5 \times {10^{ - 8}}\widehat jT$. The corresponding electric field $\overrightarrow E $ is (speed of light c = 3 × 10⁸ ms^–1)

15 $\widehat i$V / m

-15 $\widehat i$V / m

1.66 × 10^–16 $\widehat i$V / m
