\overrightarrow P \,\,.\,\,\overrightarrow Q = 0\,and\,\overrightarrow P \,\, \times \,\,\overrightarrow Q = 0

, then the angle between

\overrightarrow Q \,and\,\overrightarrow R

View answer and explanation

Correct option: B

{90^0}

Option B (

{90^0}

) is correct because if

\overrightarrow P \\. \overrightarrow Q = 0

and

\overrightarrow P \\, \times \\, \overrightarrow Q = 0

, then both vectors must be null vectors, which means any vector \overrightarrow R is perpendicular to \overrightarrow Q.
