Answer 1

question :

An object is placed at a distance of 10 cm from a convex mirror of focal length 15 cm. Find the position and nature of image.

answer:

f = +15 cm,

u = -10 cm

1/f = 1/v +1/u

1/v = 1/15 +1/10

1/v = 5/30

v = + 30 cm

The image is formed 6 cm behind the mirror; it is a virtual and erect image

hope it helps u❤

Answer 2

$\huge\boxed{\underline{\sf{\red{ᴀ}\green{ɴ}\pink{s}\orange{ᴡ}\blue{ᴇ}\pink{ʀ}}}}$

GIVEN:

Image distance (u)=-10 cm

focal length (f)=15 cm

SOLUTION:

1/f=1/v+1/u

1/v=1/f- 1/u

1/v=1/15-(- 1/10)

1/v=25/150

v=150/25

v=6 cm

object is formed behind the mirror

m= -v/u= -6/-10=0.6

the image formed is virtual erect and small
