Question
Assertion : A null vector is a vector whose magnitude is zero and direction is arbitrary.
Reason $\quad$ : A null vector does not exist.
✓

Answer

(c) If two vectors equal in magnitude are in opposite direction, then their sum will be a null vector.A null vector has direction which is intermediate (or depends on direction of initial vectors) even its magnitude is zero.
