can a physical quantity having both magnitude and direction be a vector?

Text Solution

Verified by Experts

No, it is not necessary that a physical quantity having both magnitude and direction is a vector . For example, current flowing in a conductor is having both magnitude and direction but is a scalar quantity because the laws of vector addition but is a scalar quantity because the laws of vecrtor addition are not applicable to electric current .
