Answer 1

Explanation :-

Given :-

• u= -10 cm

• f= 15 cm

To Find :-

• v = ?

• The Position and nature of the image.

Solution :-

We know the formula

• 1/f = 1/v + 1/u

Therefore, 1/v= 1/f – 1/u

Substituting the known values in the above equation we get,

=> 1/v= 1/15 + 1/10

=> 1/v = (2+3)/30 (cm)

=> v=5/30

=> v= 6cm

Nature of the image: The image is formed behind the mirror and it is virtual and erect.
