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.

Answer:

6.00

Solution:

The distance of image formed by each piece can be calculated by

$\frac{1}{f} = \frac{1}{v} - \frac{1}{u}$

$\frac{1}{10} = \frac{1}{v} - \frac{1}{- 15}$

$\Rightarrow v = 30 cm$

$|m| = \frac{30}{15} = 2$
