Answer 1

Answer:

An object of height 6 cm is placed at a distance of 15 cm from a concave mirror of focal length 10 cm. Find position, nature and height of an image. ... ( Ans : v =-30 cm, height = 12 cm, Real, inverted and magnified.

Answer 2

Explanation:

Object distance (u)= -6cm

Focal length = -10cm (concave)

By mirror Formula

1/F= 1/v+1/u

1/(-10)= 1/V+1/(-6)

-1/10=1/V-1/6

-1/10+1/6=1/V

-6+10/60=1/V

1/V= -4/60

V= 15cm

Magnification

M= -V/U

M= -15/-6

M= 2.5

Nature of Image

Image is larger than object

Image is virtual And Erect....
