MCQ
Dimensions of potential energy are
  • A
    $ML{T^{ - 1}}$
  • $M{L^2}{T^{ - 2}}$
  • C
    $M{L^{ - 1}}{T^{ - 2}}$
  • D
    $M{L^{ - 1}}{T^{ - 1}}$

Answer

Correct option: B.
$M{L^2}{T^{ - 2}}$
b
Potential energy $=[ mgh ]$

$=\left[\left( M ^1\right)\left( LT ^{-2}\right)( L )\right]$

$=\left[ ML ^2 T ^{-2}\right]$
