A) real and at a distance of 40 cm from the divergent lens
B) real and at a distance of 6 cm from the convergent lens
C) real and at a distance of 40 cm from convergent lens
D) virtual and at a distance of 40 cm from convergent lens. [JEE Main 2017]
Correct Answer: C
Solution :
As parallel beam incident on diverging lens if forms virtual image at \[{{v}_{1}}=-25\,cm\]from the diverging lense which works as a object for the converging lense (f = 20 cm) So for converging lens\[u=-40cm,f=20\,cm\] \[\therefore \] Finance image \[\frac{1}{V}-\frac{1}{-40}=\frac{1}{20}\] V = 40 cm from converging lenses.You need to login to perform this action.
