Power is defined as work done per unit time. Its formula is

Power= Work/Time
Dimensional Formula of Work= M1L2T-2 Divide it by Time T1

So Dimensional Formula of Power= M1L2T-3
SI unit of Power is Watt represented by W

    I have a question regarding this, above mentioned your final answer is M1L2T-3 but this is not in below choices. Can you please make sure either is it correct or not?

    The dimensions of power are:

    (a) ML2T-2 (b) ML 2T2
    (c) ML 2T-1 (d) ML -1T-1
