Question

A convex lens of focal length $$20$$ cm produces images of the same magnification $$2$$ when an object is kept at two distances $$x_1$$ and $$x_2$$ $$(x_1 > x_2)$$ from the lens. The ratio of $$x_1$$ and $$x_2$$ is?


A
5:3

B
2:1

C
4:3

D
3:1

Solution

The correct option is D $$3:1$$
Magnification is $$2$$
If image is real, $$x_1=\dfrac{3f}{2}$$
If image is virtual, $$x_2=\dfrac{f}{2}$$
$$\dfrac{x_1}{x_2}=3:1$$.
