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...
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.
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.
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.
Yes, you can add anything to null vector.
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.
Yes, any number can be added to a null vector.
a vector with nothing in it
Only if your zero is a null vector. You cannot add pure numbers and vectors.
They are the same.
scalar cannot be added to a vector quantity
You cannot, unless it is a null vector. As a point.
