Post Utme Unilorin 2020 Physics Question 5
Practice objective / multiple choice question 5 from the 2020 Post Utme Unilorin Physics examination.
A lens of focal length $f$ forms an image of an object at a dis\tance $u$ from the lens. The magnification of the lens is given by the equation $M = \frac{v}{u} = \frac{f}{u - f}$. If the object is placed at a dis\tance $u = 20$ cm from the lens and the focal length is $f = 10$ cm, what is the magnification of the lens?
