Question diagram: The position of the image formed by the combination of lense

Options:

Answer:

Solution:

For lens $1 : f_{1} = 10, u = - 30, v =$ ? $v = \frac{u f}{u + f} = \frac{- 30 \times 10}{- 30 + 10} = 15$ For lens 2: $f_{1} = - 10, u = 10, v =$ ? $v = \frac{u f}{u + f} = \frac{10 \times- 10}{10 - 10} = \infty$
For lens $3 : f = 30, u = - \infty, v =$ ? So v will be 30 .
