If OA is equally inclined to OX,OY ,OZ and if A is `sqrt(3)` units from the origin then the cordinates of A areA. `(3,3,3)`B. `(-1,1,-1)`C. `(-1,1,1)`D. `(1,1,1)` |

Answer» Correct Answer - D We have `l=m=n=1/(sqrt(3))` `:.vec(OA)=|vec(OA)|(lhati+mhatj+nhatk)` `impliesvec(OA)=sqrt(3)(1/(sqrt(3))hati+1/(sqrt(3))hatj+1/(sqrt(3))hatk)=hati+hatj+hatk` So, coordinates of A are `(1,1,1)`. |
