Why are length, velocity and time unsuitable as a set of base dimensions?
AVelocity is redundant, being L/T
BTime is derived from mass
CLength is dimensionless
DVelocity has no unit at all
Answer & Solution
Correct answer: A. Velocity is redundant, being L/T
Velocity is expressible as length over time, so the set is not independent and cannot yield mass.
