Vedclass · Answer

(A) The normal vector $\vec{n}$ to the plane is the vector joining the origin $(0,0,0)$ to the foot of the perpendicular $(1,2,2)$.So, $\vec{n} = (1-0)\hat{i} + (2-0)\hat{j} + (2-0)\hat{k} = \hat{i} + 2\hat{j} + 2\hat{k}$.The equation of a plane passing through a point $(x_1, y_1, z_1)$ with normal vector $\vec{n} = a\hat{i} + b\hat{j} + c\hat{k}$ is given by $a(x-x_1) + b(y-y_1) + c(z-z_1) = 0$.Substituting the point $(1,2,2)$ and the normal vector $(1,2,2)$:$1(x-1) + 2(y-2) + 2(z-2) = 0$$x - 1 + 2y - 4 + 2z - 4 = 0$$x + 2y + 2z - 9 = 0$.Thus, the correct option is $A$.

If the foot of the perpendicular from $(0,0,0)$ to the plane is $(1,2,2)$, then the equation of the plane is
