Question

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

Answer 1

Answer: (A)

0.25

Answer 2

Velocity of electromagnatic wave in space is $c=\frac{1}{\sqrt{\mu_0\epsilon_0}} \Rightarrow c=\frac{1}{\sqrt{2??}}$ $=\frac{1}{\sqrt{16}}=\frac{1}{4}=0.25$
