Correct Answer  Option 3 : ML
2T
3
Concept:
Dimensional Formula
 It depicts the way to relate any unit to fundamental Units.
 If we have to find The dimensional formula of any quantity, At first, we find its units in terms of these fundamental units, and then replace units with these dimensions.
Power

The rate of consumption of energy is called power.
P = Δ E / Δt
Δ E = Change in energy, Δt = Change in time

Unit of Power: The unit of power is Watt
1 watt = 1 Joule / 1 second
Calculation:
Dimension of Power
\(P = \frac{Dimension\ of \ Energy}{Dimension \ of \ time}\)
Dimension of Energy = Dimension of Work = Dimension of Force × Dimension of displacement
E = [ M L T ^{2} ] [ L ] = M L^{ 2} T ^{ 2}
⇒ P = E / T
\(\implies P = \frac{M L ^{2} T^{2}}{T} = M L ^{2}T^{2}T^{1}\)
⇒ P = M L ^{2} T ^{(2  1 )} = M L ^{2} T ^{3}
So, the correct option is ML2T3
