A plane Electromagnetic Waves travels in free space along x - axis. At a particular point in space, the electric field along y - axis is 9.3 Vm-1. The magnetic induction is
Answer & explanation
Correct answer: option 1
Using the relation
$c = \frac{E_0}{B_0}$
$B_0=\frac{E_0}{c}$
$ = \frac{9.3}{3×10^8}=3.1 × 10^{-8}\, T$
