Answer 2

Answer:

The image formed will be real and inverted.

The size of the image would be diminished.

Location of the image would be $30cm$ from the lens.

Explanation:

It is given that $u=-60cm\\f=+20cm$

We know the Lens formula : $\frac{1}{f} =\frac{1}{v} -\frac{1}{u}$

$\frac{1}{20} =\frac{1}{v} -\frac{1}{u}$

$\frac{1}{20} - \frac{1}{60} =\frac{1}{v}$

Therefore, $v=30cm$.

Hence we can find out that the location of the image would be $30cm$ from the lens.
