The resultant of `vecP` and `vecQ` is perpendicular to `vecP`. What is the angle between `vecP` and `vecQ`

The resultant of vecP and vecQ is perpendicular to vecR . What is the angle between vecP and vecQ

If vecP.vecQ=PQ then angle between vecP and vecQ is

If vecP.vecQ=PQ then angle between vecP and vecQ is

If vecP.vecQ=PQ then angle between vecP and vecQ is

What can be the angle between vecP+vecQ and vecP-vecQ ?

What is the angle between (vecP+vecQ) and (vecPxxvecQ)

The magnitude of the resultant of vectors vecP and vecQ is given by R^(2)=P^(2)+Q^(2) .What is the angle between vecP and vecQ .

If vecP*vecQ=0 , then angle between vecP and vecQ is 0^@ .

Magnitude of resultant of two vectors vecP and vecQ is equal to magnitude of vecP . Find the angle between vecQ and resultant of vec2P and vecQ .
