Q. A new system of units is evolved in which the values of $\mu_{0}$ and $\epsilon_{0}$ are 2 and 8 respectively. Then the speed of light in this system will be
A) 0.25
B) 0.5
C) 0.75
D) 1
Explanation
(a) The speed of light $C = \frac{1}{\sqrt{\mu_{0}\varepsilon_{0}}} = \frac{1}{\sqrt{2 \times 8}} = \frac{1}{4} = 0.25$
