The resultant of two vector `vecP and vecQ` is `vecR`. If `vecQ` is doubled then the new resultant vector is perpendicular to '`vecP`'. Then R is equal to :

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 andvecQ is vecR . If the magnitude of vecQ is doudled, the new resultant becomes perpendicuar to vecP . Then the magnitude of vecR is :

The resultant of two vectors vecP andvecQ is vecR . If the magnitude of vecQ is doudled, the new resultant becomes perpendicuar to vecP . Then the magnitude of vecR is :

The resultant of vecP and vecQ is vec R . If vecQ is doubled, vecR is doubled, when vecQ is reversed, vecR is again doubled, find P : Q : R,

vecR is the resultant of two vectors vecP and vecQ . When vecQ is reversed , the resultant is vecS . Prove that R^2+S^2=2(P^2+Q^2) .
