SATHEE: Physics And Measurement Question 87

Physics And Measurement Question 87

Question: $μ_{0}$ and $ε_{0}$ denote the permeability and permittivity of free space, the dimensions of $μ_{0} ε_{0}$ are

Options:

A) $L T^{- 1}$

B) $L^{- 2} T^{2}$

C) $M^{- 1} L^{- 3} Q^{2} T^{2}$

D) $M^{- 1} L^{- 3} I^{2} T^{2}$

Show Answer

Answer:

Correct Answer: B

Solution:

$C = \frac{1}{\sqrt{μ_{0} ε_{0}}}$

therefore $μ_{0} ε_{0} = (\frac{1}{C^{2}})$ (where C = velocity of light)

$[μ_{0} ε_{0}] = L^{- 2} T^{2}$
