Statement-I: If

\vec{a}

is perpendicular to

\vec{b}

and

\overrightarrow{{c}}

, then

\overrightarrow{{a}} \times(\overrightarrow{{b}} \times \overrightarrow{{c}})=0

Statement-II: If

\overrightarrow{{b}}

is perpendicular to

\overrightarrow{{c}}

, then

\overrightarrow{{b}} \times \overrightarrow{{c}}=0

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 the vector triple product simplifies to zero under the given conditions, while the cross product of perpendicular vectors is non-zero.
