Three vectors P → , Q → and R → are shown in the figure. Let, S be any point on the vector R → . The distance between the points P and S is b R → . The general relation among vectors P → , Q → and S → are

Step-by-step solution

Let, vector from point P to point S be C → , ⇒ C → = b R → R ^ = b R → R → R → = b R → = b Q → - P → From triangle rule of vector addition, P → + C → = S → P → + b Q → - P → = S → ⇒ S → = 1 - b P → + b Q →
