Physics And Measurement Question 125
Question: $ ML^{3}{{T}^{-1}}{{Q}^{-2}} $ is dimension of
[RPET 2000]
Options:
A) Resistivity
B) Conductivity
C) Resistance
D) None of these
Show Answer
Answer:
Correct Answer: A
Solution:
Resistivity
$ [\rho ]=\frac{[R].[A]}{[l]}\text{where }[R]=[ML^{2}{{T}^{-1}}{{Q}^{-2}}] $
$ \therefore $ $ [\rho ]=[ML^{3}{{T}^{-1}}{{Q}^{-2}}] $
