# If momentum (P), area (A), and time (T) are taken to be fundamental quantities, then energy has the dimensional formulaa)b) c) d)

The answer is the option d)

Explanation: Let us consider as the formula for energy for fundamental quantities P, A & T.

Thus, dimensional formula of-

Energy(E) =

Momentum (P) =

Area (A) =

Time(T) =

Now, E = f.s

Now, let us compare the powers,

Thus, is the dimensional formula of energy.
