A physical quantity which has a direction:-
A physical quantity which has a direction:-
Open in App
Solution
The correct option is A may be a vector
A vector quantity has direction and magnitude both but a 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.
The vector should also obey the triangular law of vectors. Hence, we can say that a given quantity may be a vector.
