2. A convex lens with focal length f centimeters will project the image of an object on a point behind the lens. If an object is placed a distance of p centimeters from the lens, then the distance q centimeters of the image from the lens is related to p and f by the lens equation: (1/p) + (1/q) = (1/f) Diagram looks like this: f || p q I am having trouble wit this problem: B. Find an expression that gives q as a function of p, assuming that the focal length is a constant of 5 centimeters.

Question

2. A convex lens with focal length f centimeters will project the image of an object on a point behind the lens. If an object is placed a distance of p centimeters from the lens, then the distance q centimeters of the image from the lens is related to p and f by the lens equation: (1/p) + (1/q) = (1/f)

Diagram looks like this:
                    f 
|<------@----(lens)----@----->|
           p                           q

I am having trouble wit this problem: 
B. Find an expression that gives q as a function of p, assuming that the focal length is a constant of 5 centimeters.
