The dimensions of power are
  • ✓
    $M^1 L^2 T^{-3}$
  • B
    $M^2 L^1 T^{-2}$
  • C
    $M^1 L^2 T^{-1}$
  • D
    $M^1 L^1 T^{-2}$
✓

Answer

Correct option: A.
$M^1 L^2 T^{-3}$
(a) Power $=\frac{\text { Work done }}{\text { Time }}=\left[\frac{M L^2 T^{-2}}{T}\right]=\left[M L^2 T^{-3}\right]$
