Two converging lenses, A with a focal length of +10.0cm and B with a focal length of +12.0cm, are placed 40cm apart. An object 4.0cm high is placed 15.0cm to the left of lens A. Determine the position and magnification of the final image produced by the lens pair by two methods:
A) by graphical construction, to scale, with a measurement of the
