Question

A vector having zero magnitude then it is called as
1)null vector
2)zero vector
3)both a and b .
4)none of these​

Answer 1

Answer:

both a and b zero vector or null vector

Answer 2

3) Both a and b null vector and Zero vector are a vector having zero magnitude

Explanation:

• Two vectors have the same magnitude and are in opposite indirection and their sum is known as the Null vector.

• Its magnitude is zero.

• Its direction depends on the initial vectors.

• The addition or subtraction of a zero vector from a vector is again the same vector.$\[\overset{\to }{\mathop{A}}\,+\overset{\to }{\mathop{0}}\,=\overset{\to }{\mathop{A}}\,\]$

• So, the Zero vector is also known as the Null vector.
