Assuming force, length, and time to be the fundamental quantities, determine the dimensions of momentum.

Options

A $F^2T$
B $FT^{-1}$
C $FT$
D $FLT^{-1}$

Correct answer

C. $FT$

Step-by-step solution

The dimensional formula for momentum is

[p] = MLT^{-1}

.

The dimensional formula for force is

[F] = MLT^{-2}

.

We can express the dimensions of momentum as

[p] = (MLT^{-2}) \times T

.

Substituting the fundamental quantity force

F

and time

T

, we get

[p] = FT

.
