A parallel beam of light is incident on the system of two convex lenses of focal length `f_(1)=20cm` and `f_(2)=10cm` . What should be the distance between the two lenses so that rays after refraction from both the lenses pass undeviated?  img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/BMS_V04_C01_E01_196_Q01.png" width="80%"
