Question

If length time and energy are fundamental units then find the dimension of mass

Answer 1

Answer:

e = m$c^{2}$

m = e/$c^{2}$

Dimension of e is $L^{0 }E^{1}T^{0}$ and Dimension of c is $L^{1}E^{0}T^{-1}$

m =$L^{0 }E^{1}T^{0}$ / $(L^{1}E^{0}T^{-1})^{2}$

Therefore, dimensions of mass is $L^{-2}E^{1}T^{2}$
