# Find the position

Answer :  To find: position vector of the foot of perpendicular and the perpendicular distance from the point P to given plane and the image of P in the plane.

Formula used:       Therefore,                Hence, position vector of the foot of perpendicular and the perpendicular distance from the point P to given plane are Let Q be the image of the point P to the given plane

PQ will be normal to the plane

Therefore, equation of PQ is As Q lies on line PQ, the position vector of Q is  Let R is mid-point of PQ. Position vector of R is   R will also lie on the plane.           Put the value of λ = 1:   Rate this question :
