An object is located in a fixed position in front of a screen. Sharp image is obtained on the screen for two positions of a thin lens separated by $\displaystyle 10$ cm. The size of the images in two situations are in the ratio $\displaystyle 3$ : 2. What is the distance between the screen and the object ?
Official answer
(4)
99.$\displaystyle 0$ cm
