(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

At one instant, the electric and magnetic fields at one point of an electromagnetic wave are E = 300i + 50j − 200k V/m, and B = Bsub0 (1.7i − 3.9j + ak μT.

(a) What are the values of a and B0?

(b) What is the Poynting vector at this time and position?

2. Relevant equations

E = Bc

s = (E x B) / (mu sub0)

3. The attempt at a solution

i tried to find Bsub0 using the equation E = Bc for the i and j vectors but the answers are inconsistent. any help would be appreciated
