Statement-I: If dot product and cross product of

\vec{a}

and

\vec{b}

are zero, it implies that one of the vector

\vec{a}

and

\vec{b}

must be a null vector.
Statement-II: Null vector is a vector with zero magnitude.

View answer and explanation

Correct option: A

Statement-I is true and statement-II is true

Statement-I is true because if both the dot product and cross product are zero, at least one of the vectors must be a null vector. Statement-II is true because a null vector is defined as a vector with zero magnitude.
