Answer: (3) The assertion is true but the reason is false.

Explanation:

The relative speed, that is, the subtraction of the vectors of two speeds, will also be a vector in the form of speed, so its dimensional formula does not change. Relative speed is measured not by calculating ratios, but by calculating differences.
