Two vectors `vecP` and `vecQ` that are perpendicular to each other are :A. `(vecPxxvecQ)/(P.Q)`B. `(vecPxxvecQ)/(sin theta)`C. `(vecpxxvecQ)/(PQ sin theta)`D. `(vecPxxvecQ)/(PQ sin theta)` |

Answer» Correct Answer - B `vecPxxvecQ=(PQ sin theta)hatn` `hatn` is a unit vector `bot` to plane of `vecP` and `vecQ` `hatn=(vecPxxvecQ)/(PQ sin theta)=((vecP)/(P))xx((vecQ)/(Q))xx(1)/(sin theta)=(hatPxxhatQ)/(sin theta)` |
