The resultant of two vectors `vec(P)` and `vec(Q)` is `vec(R)`. If `vec(Q)` is doubled then the new resultant vector is perpendicular to `vec(P)`. Then magnitude of `vec(R)` is :-

The resultant of two vectors vec(P) and vec(Q) is vec(R ) . If the magnitude of vec(Q) is doubled, the new resultant vector becomes perpendicular to vec(P) . Then, the magnitude of vec(R ) is equal to

The resultant of two vectors vec(P) and vec(Q) is vec(R ) . If the magnitude of vec(Q) is doubled, the new resultant vector becomes perpendicular to vec(P) . Then, the magnitude of vec(R ) is equal to

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.

Two forces vec(P) and vec(Q) are acting at a point. If vec(P) is reversed, the new resultant becomes perpendicular to the initial resultant. Then:

The resultant and dot product of two vectors vec(a) and vec(b) is equal to the magnitude of vec(a) . Show that when the vector vec(a) is doubled , the new resultant is perpendicular to vec(b) .

If the resultant of two vectors vec P and vec Q is given by R^(2) = P^(2) + Q^(2) , then the angle between the vectors vec P and vec Q is _____.
