બળ $(F)$,લંબાઇ $(L)$ અને સમય $(T)$ મૂળભૂત એકમો હોય,તો દળનું પારિમાણીક સૂત્ર નીચેના પૈકી કયુ થશે?

A

$ F{L^{ - 1}}{T^2} $

B

$ F{L^{ - 1}}{T^{ - 2}} $

C

$ F{L^{ - 1}}{T^{ - 1}} $

D

$ F{L^2}{T^2} $

Solution

(a) Let $m = K{F^a}{L^b}{T^c}$

Substituting the dimension of $[F] = [ML{T^{ – 2}}],$

$[C] = [L]\;and\;[T] = [T]$ and comparing both sides,

we get $m = F{L^{ – 1}}{T^{ – 2}}$
