Vedclass · Answer

(b) $E = K{F^a}{A^b}{T^c}$

$\left[ {M{L^2}{T^{ - 2}}} ight] = {\left[ {ML{T^{ - 2}}} ight]^a}{\left[ {L{T^{ - 2}}} ight]^b}{\left[ T ight]^c}$

$\left[ {M{L^2}{T^{ - 2}}} ight] = \left[ {{M^a}{L^{a + b}}{T^{ - 2a - 2b + c}}} ight]$

$	herefore $ $a = 1$, $a + b = 2$ $&rArr;$ $b = 1$

and $ - 2a - 2b + c = - 2\;\; \Rightarrow \;c = 2$

$	herefore $ $E = KFA{T^2}$.
