Answer:

Power is defined as the rate of doing work.

The work is done per unit time.

Power (P) ∝ Work (W)

Power (P) ∝ 1 / Time (t)

So, P = W / t

W = Force (F) × Distance (d)

So, P = (F × d) / t

Velocity (V) = Distance (d) / time (t)

So, P = F.V

SI unit of power is watt (W)

P = (F × d) / t

dim[P] = \frac{dim[F] * dim[d]}{dim[t]} \\\\dim[P] = \frac{[MLT^{-2} ]*[L]}{[T]}\\\\dim[P] = [ML^{2}T^{-3}]

So, the dimension of power is [ML²T⁻³]
