Question

an object is placed at 4 cm distance in front of a concave mirror of radius of curvature 24cm find the position of image is the image magnified​

Answer 1

as given

u = -4

v = ?

f = -24/2 = -12

by mirror formula

1/f = 1/v - 1/u

1/f + 1/u = 1/v

1/(-12) + 1/(-4) = 1/v

-1/12 - 1/4 = 1/v

(-1-3)/12 = 1/v

-4/12 = 1/v

-1/3 = 1/v

hence, v = -3

the image will form at 3cm away from the image

Answer 2

ur answer is in picture hope it helps
