NEET Solved Paper 2014 Question 1
Question: If force (F) velocity ( $ \upsilon $ ) and time (T) are taken as fundamental units, then the dimensions of mass are [AIPMT 2014]
Options:
A) $ [Fv{T^{-1}}] $
B) $ [Fv{T^{-2}}] $
C) $ [F{v^{-1}}{T^{-1}}] $
D) $ [F{v^{-1}}T] $
Show Answer
Answer:
Correct Answer: D
Solution:
We know that
$ F=ma\Rightarrow F=\frac{mv}{t}\Rightarrow m=\frac{Ft}{v} $
$ [M]=\frac{[F][T]}{[v]}=[F{v^{-1}}T] $
