Two vector ` vec P` and ` vec Q` act at a point and have a resultant ` R_1. If `vec Q` is replaced by the vevtor ` ( vec (R_1^2-P^2)/Q` show tht the reaultant is still of magnitude ` vec R_1`.

Two vectors vec(P) " and "vec(Q) are added, the magnitude of resultant is 15 units. If vec(Q) is reversed and added to vec(P) resultant has a magnitude sqrt(113) units. The resultant of vec(P) and a vector perpendicular vec(P) and equal in magnitude to vec(Q) has a magnitude

If P ,Q and R are three collinear points such that vec P Q= vec a and vec Q R = vec bdot Find the vector vec P R .

If vec P and vec Q are two vectors, then the value of (vec P + vec Q) xx (vec P - vec Q) is
