The vector equation of a plane is a relation satisfied by position vectors of all the points on the plane. If P is a plane and hat(n) is a unit vector through origin which is perpendicular to the plane P then vector equation of the plane must be rcdothat(n)=d where d represents perpendicular distance of plane p from origin Q. The position vector of the image of the point a in the plane rcdothat(n)=d must be (dne0)

Answer»

`-acdothat(N)`
`a-2(d-ahat(n))HAT(n)`
`a+2(d-ahat(n))hat(n)`
