    1. The problem statement, all variables and given/known data
    1011688.jpg
    If the focal length of the concave lens is -7.50 cm, at what distance d_o from the lens should an object be placed so that its image is formed 3.70 cm from the lens?
    What is the magnification m produced by the concave lens described in above?
    Where should the object be moved to have a larger magnification?

    a) The object should be moved closer to the lens.
    b) The object should be moved farther from the lens.
    c) The object should be moved to the focal point of the lens.
    d) The object should not be moved closer to the lens than the focal point.
