It has the role of the identity element - same as, in the case of real numbers, the zero for addition, and the one for multiplication.

What is null vector?

NULL VECTOR::::null vector is avector of zero magnitude and arbitrary direction the sum of a vector and its negative vector is a null vector...


Can you add zero in null vector?

no,zero cannot be added to a null vector because zero is scalar but null vector is a vector,although null vector has zero magnitude but it has direction due to which it is called a vector.


Can a null vector be added to zero?

No, a vector cannot be added to a scalar. You could multiply a null vector by zero (and you'd get the null vector), but you can't add them.


What is different between negative vector and null vector?

A null vector has no magnitude, a negative vector does have a magnitude but it is in the direction opposite to that of the reference vector.


Can you add 0 to null vector?

Yes, you can add anything to null vector.


How do you add two null vectors by following vector laws of addition?

The sum of two null vectors is a null vector. And since a direction is not relevant for a null vector, the resultant has no direction either.


Can you add 0 to a null vector?

Yes, any number can be added to a null vector.


What is meant by null vector?

a vector with nothing in it


Can you add zero in a null vector?

Only if your zero is a null vector. You cannot add pure numbers and vectors.


What is the difference between zero vector and null vector?

They are the same.


How can a null vector be a vector if there is no direction?

It has magnitude 0 and a direction and obeys vector laws, so is a vector


Can you add zero to a null vector?

scalar cannot be added to a vector quantity
