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{j} T. The corresponding electric field \overrightarrow{E} is (speed of light c = 3 x 108 ms-1)


Option: 1 -1.66 \times 10^{-16} \widehat{i} V/m

Option: 2 1.66 \times 10^{-16} \widehat{i} V/m

Option: 3 -15\widehat{i} V/m

Option: 4 15\widehat{i} V/m
