Answer 1

Answer:

Virtual, upright and enlarged

Answer 2

ANSWER:

d) Virtual, upright and enlarged.

STEP-BY-STEP EXPLANATION:

Given that a converging lens has a focal length of 15 cm. And an object is placed 10 cm from the optical centre of the lens.

We need to find out the characteristics of the image formed.

The first point to notice in the question is that "converging lens". Converging lens means convex lens while diverging lens means concave lens. So, here the lens is convex lens having focal length (f) 15 cm.

Now, an object has been placed 10 cm away from optical centre. So, we can say that the object is placed between focus & optical centre and object distance is 10 cm.

Since, the object is between focus and optical centre; the formed image will be magnified (enlarged), virtual , upright and will be formed same side of the object of the lens.

Therefore, the characteristics of the image formed is virtui, upright and enlarged.
