Question

a unit vectors is unit less & dimensional true or false​

Answer 1

Answer:

false

Explanation:-

Since we have the same numerical value in numerator and the denominator, a unit vector has a magnitude of 1 unit. Likewise, we have the same unit in both numerator and the denominator, that makes a unit vector 'unitless', and hence dimensionless. That's why I think a unit vector has no dimensions.
