Question 183: Units , Dimensions and Error Analysis

Question

A quantity x is given by $\left( {{{IF{v^2}} \over {W{L^4}}}} \right)$ in terms of moment of inertia I, force F, velocity v, work W and
Length L. The dimensional formula for x is same as that of :

Accepted Answer

x = $\left( {{{IF{v^2}} \over {W{L^4}}}} ight)$
$ 	herefore $ [x] = ${{\left[ {M{L^2}} ight]\left[ {ML{T^{ - 2}}} ight]{{\left[ {L{T^{ - 1}}} ight]}^2}} \over {\left[ {M{L^2}{T^{ - 2}}} ight]{{\left[ L ight]}^4}}}$
= [ML
-1
T
-2
]
