Question 93: Units , Dimensions and Error Analysis

Question

If mass is written as $$m=k \mathrm{c}^{\mathrm{P}} G^{-1 / 2} h^{1 / 2}$$ then the value of $$P$$ will be : (Constants have their usual meaning with $k a$ dimensionless constant)

Accepted Answer

$$\begin{aligned}
& \mathrm{m}=\mathrm{kc}^{\mathrm{P}} \mathrm{G}^{-1 / 2} \mathrm{~h}^{1 / 2} \
& \mathrm{M}^1 \mathrm{~L}^0 \mathrm{~T}^0=\left[\mathrm{LT}^{-1}ight]^{\mathrm{P}}\left[\mathrm{M}^{-1} \mathrm{~L}^3 \mathrm{~T}^{-2}ight]^{-1 / 2}\left[\mathrm{ML}^2 \mathrm{~T}^{-1}ight]^{1 / 2}
\end{aligned}$$
By comparing $$\mathrm{P}=1 / 2$$
