Statement-I: A null vector is a vector whose magnitude is zero and direction is arbitrary.
Statement-II: A null vector does not exist.

View answer and explanation

Correct option: B

Statement-I is true and statement-II is false

Option B (Statement-I is true and statement-II is false) is correct because a null vector has zero magnitude and arbitrary direction, and therefore it exists.
