A point object is placed as shown. The two pieces are of the same lens of focal length 10   cm . Find the distance (in cm ) between the two images formed by two pieces of the lens.

Correct answer

6

Step-by-step solution

The distance of image formed by each piece can be calculated by 1 f = 1 v - 1 u 1 10 = 1 v - 1 - 15 ⇒ v = 30   cm m = 30 15 = 2
