The SI unit of the quantity \(\frac{|E|}{|B|}\) is :
Answer: B
The SI unit of \(\frac{|E|}{|B|}\) is m/s.
From the Lorentz force, \(qE\) and \(qvB\) are both forces, so \(E\) and \(vB\) have the same units and \(\frac{E}{B}\) has the units of velocity. For an electromagnetic wave in vacuum \(\frac{E}{B} = c\). Explicitly, (V/m)/T = (V/m)/(V s/m2) = m/s.
s/m is the inverse, and the options with \(c^{2}\) put a speed squared where none belongs.
