If two non-parallel vectors

\vec{A}

and

\vec{B}

are equal in magnitude, then the vectors

(\vec{A}-\vec{B})

and

(\vec{A}+\vec{B})

will be

View answer and explanation

Correct option: C

Perpendicular to each other

Option C (Perpendicular to each other) is correct because the dot product of

(\vec{A}-\vec{B})

and

(\vec{A}+\vec{B})

is zero, indicating perpendicularity.
