Two point sources \(S_1\) and \(S_2\) are \(24 \mathrm{~cm}\) apart. Where should a convex lens of focal length \(9 \mathrm{~cm}\) be placed in between them, so that the images of both sources are formed at the same place?
- A 8 cm
- B 12 cm
- C 6 cm
- D 10 cm
Answer & Solution
Correct Answer
(B) 12 cm
Step-by-step Solution
Detailed explanation
The given condition will be satisfied only if one source \(\left(S_1\right)\) placed on one side such that \(u < f\) (i.e. it lies under the focus. The other source \(\left(S_2\right)\) is placed on the other side of the lens such that \(u>f\) (i.e. it lies beyond the focus). If…
