Assertion: A physical quantity cannot be called as a vector if its magnitude is zero.
Reason: A vector has both, magnitude and direction.

Statement I: A physical quantity cannot be called a vector if its magnitude is zero. Statement II: A vector has both magnitude and direction.

(A): A physical quantity cannot be called as a vector if its magnitude is zero. (R): A vector has both magnitude.direction without satisfying vector addition properties.

A vector with magnitude zero is called a

Assertion : A physical quantity can be regarded as a vector, if magnitude as well as direction is associated with it. Reason: : A physical quantity can be regarded as a scalar quantity, if it is associated with magnitude only.

A physical quantity which has a direction and magnitude

Assertion (A) : Displacement is a vector. Reason ( R) : Displacement has both magnitude and direction.
