Explanation Given Data: ( s near ) 0 = 90 cm s near = 10 cm Formula Used: Consider the expression for refractive power of a lens. P = 1 f Here, f is the focal length of the lens. Consider the expression for lens formula. 1 f = 1 s + 1 s ′ Here, s ′ is the image distance from the center of lens, s is the object distance from the center of lens, and f is the focal length of the lens. Substitute P for 1 f , P = 1 s + 1 s ′ (1) Explanation: The power of O (person) with the magnifying lens is, P = P min + P lens Modify the expression by using the expression in equation (1) as follows. 1 s near + 1 s ′ = 1 ( s near ) 0 + 1 s ′ +
