SUMMARY
The problem involves finding the distance between two positions of a converging lens with a focal length of 4.2 cm, given that the total distance between the object and image is fixed at 40.0 cm. Utilizing the lens equation 1/p + 1/q = 1/f, where p is the object distance and q is the image distance, the relationship p + q = 40 must also be applied. By solving these two equations simultaneously, one can determine the distance 'a' between the two lens positions.
