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,

The resultant of vec(P) and vec(Q) is vec(R) . If vec(Q) is doubled, vec(R) is doubled, when vec(Q) is reversed, vec(R) is again doubled. Find P:Q:R.

The resultant of forces vecP and vecQ is vecR. If vecQ is doubles then vecR is doubled. If the direction of vecQ is reversed then vecR is again doubled . Then P^2:Q^2:R^2 is (A) 3:1:1 (B) 2:3:2 (C) 1:2:3 (D) 2:3:1

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