The same sort of reasoning that zero is a number. It ensures that the set of all vectors is closed under addition and that, in turn, allows the generalization of many operations on vectors.
Also, the way we got around the concept of having something with zero magnitude also have a direction is pretty cool. We made it up! In abstract algebra it's perfectly OK to constrain a specific algebraic structure with rules (called axioms) that the structure must follow.
In your example, the algebraic structure that vectors are in is called a "vector space." One of the axioms that define a vector space is:
"An element, 0, called the null vector, exists in a vector space, v, such that v + 0 = vfor all of the vectors in the vector space."
Ta Da!! Aren't we clever?
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.
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.

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, 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.

a vector with nothing in it
The null vector, also called the zero vector, is a vector a, such that a+b=b for any vector b. Also, b+( -b)=a An example in R3 is the vector <0,0,0> Here are some examples of its use <2,2,2>+<-2,-2,-2>=<0,0,0> <2,2,2>+<0,0,0>=<2,2,2>
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
