Question

A plane electromagnetic wave of frequency 100 MHz is traveling in a vacuum along the x - direction. At a particular point in space and time, B → = 2 . 0 × 10 - 8 k ^ T · (where, k ^ is unit vector along z - direction) What is E → at this point?, 0 . 6 j ^ V m - 1, 6 . 0 k ^ V m - 1, 6 . 0 j ^ V m - 1, 0 . 6 k ^ V m - 1

MARKS App · Accepted Answer

E = B C = 6 . (Direction of the wave) ‖ ( E → × B → ) ⇒ i ^ = j ^ × k ^ ⇒ E → = 6 j ^ V m - 1
