You place your eye 5.0 cm to the left of a magnifying glass of focal length 2.1 cm. You place an object to the right of the magnifying glass, somewhere between the vertex and focus. (a) Starting from the formula for angular magnification M derived in class, show that in this case, M is a *minimum* when the image is at the near point (25 cm), and a *maximum* when the image is at the far point of the eye. (b) Find these min and max values for M. (c) If the image is at the eye's near point, find the object distance (the distance of the object from the lens vertex)
