1.Units, Dimensions and Measurement

The dimensions of the product $\mu_{0} \varepsilon_{0}$ are related to those of velocity as
A$(velocity)^2$
B$velocity$
C$1/velocity$
D$1/(velocity)^2$
Solution
$C=\frac{1}{\sqrt{\mu_{0} \varepsilon_{0}}}$
$\mu_{0} \varepsilon_{0}=\frac{1}{\mathrm{C}^{2}}=\frac{1}{(\mathrm{velocity})^{2}}$
$\mu_{0} \varepsilon_{0}=\frac{1}{\mathrm{C}^{2}}=\frac{1}{(\mathrm{velocity})^{2}}$
