The intensity of a light source at a distance is directly
proportional to the strength of the source and inversely
proportional to the square of the distance from the source. Two
light sources, one five times as strong as the other, are 9 m
apart. At what point on the line segment joining the sources is the
intensity the weakest? Write an equation representing the
intensity, I, at a distance, x, from the weaker lightbulb, and with
k as the...

23.28:At a certain distance from a point charge, the potential and electric field magnitude due to that charge are 4.98 V and 12.0 V/m, respectively. (Take the potential to be zero at infinity.) 1.What is the distance to the point charge? (d= ? m) 2.What is the magnitude of the charge? (q= ? c)
The illumination of an object by a light source is directly proportional to the strength of the source and inversely proportional to the square of the distance from the source
The illumination of an object by a light source is directly proportional to the strength of the source and inversely proportional to the square of the distance from the source. If two light sources, one four times as strong as the other, are placed 11 ft apart, how far away from the stronger light source should an object be placed on the line between the two sources so as to receive the least illumination?
