Suppose that the intensity of a point light source is directly proportional to the strength of the source and inversely proportional to the square of the distance from the source. Two point light sources with strengths of S and 27S are separated by a distance of 40 cm. Where on the line segment between the two sources is the intensity a minimum? The intensity on the line segment between the two sources is a minimum at the point located i cm from the light source with strength of S.
