If force (F), velocity (V) and time (T) are taken as fundamental units, then the dimensions of mass are:
[F V T-1]
[F V T-2]
[F V-1 T-1]
[F V-1 T]
F = MA
F = MV/T
= [M] = [F1T1V-1]
Option 1)
[F V T-1]
This is the incorrect option
Option 2)
[F V T-2]
This is the incorrect option
Option 3)
[F V-1 T-1]
This is the incorrect option
Option 4)
[F V-1 T]
This is the correct option
