1.Units, Dimensions and Measurement
easy
Dimensions of potential energy are
A$ML{T^{ - 1}}$
B$M{L^2}{T^{ - 2}}$
C$M{L^{ - 1}}{T^{ - 2}}$
D$M{L^{ - 1}}{T^{ - 1}}$
Solution
Potential energy $=[ mgh ]$
$=\left[\left( M ^1\right)\left( LT ^{-2}\right)( L )\right]$
$=\left[ ML ^2 T ^{-2}\right]$
$=\left[\left( M ^1\right)\left( LT ^{-2}\right)( L )\right]$
$=\left[ ML ^2 T ^{-2}\right]$
