SATHEE: Physics And Measurement Question 95

Physics And Measurement Question 95

Question: Dimensions of permeability are

[CBSE PMT 1991; AIIMS 2003]

Options:

A) $A^{- 2} M^{1} L^{1} T^{- 2}$

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

C) $M L^{0} T^{- 1}$

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

Show Answer

Answer:

Correct Answer: A

Solution:

$F = \frac{μ_{0}}{4 π} \frac{2 I_{1} I_{2} l}{r}$

$\Rightarrow$ $μ_{0} = [F] {[A]}^{- 2} = [M L T^{- 2} A^{- 2}]$
