Two vectors `vecP and vecQ` are inclined to each other at angle `theta`. Which of the following is the unit vector perpendicular to `vecP and vecQ` ?

Two vectors vecP and vecQ that are perpendicular to each other are :

Two vectors vecP and vecQ that are perpendicular to each other are :

Two vectors vecP and vecQ that are perpendicular to each other if :

If vecP=i+j+2k and vecQ=3i-2j+k , the unit vector perpendicular to both vecP and vecQ is

If vecP=i+j+2k and vecQ=3i-2j+k , the unit vector perpendicular to both vecP and vecQ is

The resultant of two vectors vecP and vecQ is vecR . If the magnitude of vecQ is doubled, the new resultant becomes perpendicular to vecP , then the magnitude of vecR is

The resultant of two vectors vecP and vecQ is perpendicular to the vector vecP and its magnitude is equal to half of the magnitude of vector vecQ . Then the angle between P and Q is
