Physics And Measurement Question 149
Question: Dimension of $ R $ is?
[AFMC 2003; AIIMS 2005]
Options:
A) $ ML^{2}{{T}^{-1}} $
B) $ ML^{2}{{T}^{-3}}{{A}^{-2}} $
C) $ M{{L}^{-1}}{{T}^{-2}} $
D) None of these
Show Answer
Answer:
Correct Answer: B
Solution:
$ R=\frac{V}{I} $
$ =[ \frac{ML^{2}{{T}^{-3}}{{A}^{-1}}}{A} ] $ = $ [ML^{2}{{T}^{-3}}{{A}^{-2}}] $
