Question

The physical quantity ------ doesn't have a direcation

Answer 1

Answer:

A vector quantity has direction and magnitude both but scalar has only magnitude. If we consider null vector , it has zero magnitude and it has no direction or may have direction. Generally the null vector is the resultant of two equal magnitude and opposite direction vectors. So we can say that the given quantity may be a vector.

Vector should also obey triangular law of vectors.Hence, we can say that given quantity may be vector
