Question:

If force (F), velocity (V) and time (T) are taken as fundamental units, then the dimensions of mass are :

Options:

[F V T-1]

[F V T-2]

[F V-1 T-1]

[F V-1 T]

Correct Answer:

[F V-1 T]

Explanation:

Force : F = ma

acceleration : a = \(\frac{velocity}{time}\)

⇒ F = \(\frac{mv}{t}\)

and, m = \(\frac{Ft}{v}\)
