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 are not applicable to electric current .
