Find the focal length of the lens

Reference no: EM13248743

A near-sighted woman cannot focus on any object farther away than a distance x = 57 cm. Find the focal length of the lens which will correct her vision. (If an object is very far away, the lens should produce an image a distance x in front of her eyes so that she can focus on it.) Neglect the distance between the lens and the eye.
