. What should be the distance of an object from a converging lens of focal length 10 cm if it is to be seen clearly by a normal human eye kept close to the optical centre of the lens?

Options:

Answer:

Solution:

$v = - 25 cm, f = + 10 cm$

$\frac{1}{- 25} - \frac{1}{u} = \frac{1}{10} \Rightarrow u = \frac{- 25.10}{25 + 10} = \frac{- 50}{7}$
