Question:

A plane electromagnetic wave of frequency 50 MHz travels in free space in the X- direction. At a particular point in space and time, the magnetic field is 0.003 G in the Z-direction. The magnitude and direction of the electric field is

Options:

9 V/m, along the negative Y-direction

$1 × 10^{-15} V/m$ along the Y-direction

90 V/m along the Y-direction

$1 × 10^{15} V/m$ along the Y-direction

Correct Answer:

90 V/m along the Y-direction

Explanation:

The correct answer is Option (3) → 90 V/m along the Y-direction
