Question

what is null or zero vector​

Answer 1

• Zero Vector or null vector is a vector which has zero magnitude and an arbitrary direction. It is represented by 0 .

• If a vector is multiplied by zero, the result is a zero vector. ... The velocity vector of a stationary body is a zero vector.

Zero Vector or null vector is a vector which has zero magnitude and an arbitrary direction.

It is represented by 0 .

If a vector is multiplied by zero, the result is a zero vector.

The identity element of vector space is known as zero or null vector.

If we take the number 0 it has no magnitude and it can be given any sign.

Example-1.Two people pulling a rope in opposite direction with equal force.

Property-When we subtract zero vector to
