The dimension of power is
-
ML\(^2\)T\(^{-3}\)
- ML\(^1\)T\(^2\)
- ML\(^2\)T\(^{-2}\)
- MLT\(^2\)
The correct answer is: A
Explanation
POWER = \(\frac{\text{workdone}}{\text{time}}\)
Dimension of work done ( F x S = M x A x S ) = MLT\(^{-2}\) L = ML\(^2\)T\(^{-2}\)
Dimension of time = T
Therefore, the dimension of power = \(\frac{ML^2T^{-2}}{T}\) = ML\(^2\)T\(^{-3}\)
