Question 41 of 75 in this shift, Physics question 16 of 25, Section A.

An object ABAB is placed 15 cm on the left of a convex lens PP of focal length 10 cm. Another convex lens QQ is now placed 15 cm right of lens PP. If the focal length of lens QQ is 15 cm, the final image is __________.
  1. (1)virtual, formed at 7.5 cm right of lens QQ, with a size bigger than that of ABAB
  2. (2)real, formed at 7.5 cm right of lens QQ, with a size same as that of ABABOfficial answer
  3. (3)formed at infinity.
  4. (4)real, formed at 7 cm right of lens QQ, with a size smaller than that of ABAB
