the vectorIf A-. A cos θ i + Aperpendicular to A is given by,(1) Bcos θ i-Bsin θ J(2) B sin θ 1-B cos θ jsin θ j, then(4)Bsín θ 1 + B cosθ J |

Answer» For a perpendicular vector.. the dot product should be 0. so only option is 2. as dot product is. (Acos∅)(Bsin∅) -(Asin∅)(Bcos∅) = ABsin∅cos∅ -ABsin∅cos∅ = 0 |
