Vedclass · Answer

(B) Let the origin be $O(0,0,0)$ and the foot of the perpendicular from the origin to the plane be $P(2,-1,3)$.Since $OP$ is perpendicular to the plane, the vector $\vec{OP}$ is the normal vector to the plane.The direction ratios of the normal vector $\vec{OP}$ are $(2-0, -1-0, 3-0) = (2, -1, 3)$.The equation of a plane passing through a point $(x_1, y_1, z_1)$ with normal vector $(a, b, c)$ is given by $a(x-x_1) + b(y-y_1) + c(z-z_1) = 0$.Substituting the point $P(2, -1, 3)$ and the normal vector $(2, -1, 3)$ into the equation:$2(x-2) - 1(y-(-1)) + 3(z-3) = 0$$2(x-2) - 1(y+1) + 3(z-3) = 0$$2x - 4 - y - 1 + 3z - 9 = 0$$2x - y + 3z - 14 = 0$Thus, the equation of the plane is $2x - y + 3z - 14 = 0$.

If $(2,-1,3)$ is the foot of the perpendicular drawn from the origin to the plane, then the equation of the plane is
