5 cm high object is placed at a distance of 10 cm from a convex lens of focal length 15 CM by drawing a ray diagram find position nature and size of image

Answer 1

hey there! here is ur answer! Hope it helps!

Answer 2

Answer:

h = 5 cm

u = -10 cm

f= 15 cm

v=?

h' = ?

using lens formula :

-1/u + 1/v = 1/f

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

1/v = 1/15- 1/10

1/v = 2-3/30

1/v = -1/30

v = - 30

m= h'/h = v/u

m= h' /5 = -30/-10

h' = 30×5/10

h' = 15 cm

the image is virtual and erect
