SATHEE: Physical World Units and Measurements

Physical World Units and Measurements - Result Question 11

11. If force (F), velocity (V) and time (T) are taken as fundamental units, then the dimensions of mass are :

[2014]

(a) $[F V T^{- 1}]$

(b) $[F V T^{- 2}]$

(d) $[F V^{- 1} T]$

Show Answer

Answer:

Correct Answer: 11. (d)

Solution:

(d) Force $=$ mass $\times$ acceleration

$\Rightarrow$ Mass $= \frac{force}{acceleration}$

$= \frac{force}{velocity / time} = [F V^{- 1} T]$
