The number of lines that can be drawn through the point P at a distance of d meters from the point Q if PQ>d are

Draw a circle having centre at  P and radius d meters. If the point Q  lies inside the circle then the lines drawn through the point P at a distance of d units is zero.If the point Q  lies on the circle then the lines drawn through the point P at a distance of d units is one.If the point Q  lies outside the circle then the lines drawn through the point P at a distance of d units is two. Here,  PQ>dIt means the point Q  lies outside the circleTherefore, the number of lines drawn through the point P at a distance of d units is two
