Answer 2

The image formed will be real Diminished and inverted.

Explanation:

Here we have H 1 as 1 cm, The distance of the image formed is given as -15 cm.

And the focal length of the object is given as -10 CM.

On applying the lens formula and putting the above given values of you and if we get we or distance of the object as:-

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

⇒ v= -30 cm

Now since we get the value of v as -30.

We can calculate the magnification of the object we get by applying the formula, m $= \frac {h_{2}}{h_{1}}$

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

⇒$\frac{30}{-15}$

⇒ $h_{2}$ = -2

So from the answers in solutions,

We get we can figure out that the image formed will be real Diminished and inverted.
