Question

an object is placed at the distance of 10 cm from a convex mirror of focal length15 cm.find the position of image.​

Answer 1

Answer:

u= -10 cm

f= -15 cm

1/v+1/u =1/f

1/v= 1/-15 - 1/-10

1/v= 1/30

v= 30 cm

Therefore , the image is placed behind the mirror at a distance of 30 cm

Answer 2

Answer:

v=6cm

Explanation:

u=-10cm

f=15cm

v=?

we have to find v,

Using mirrors formula,

1/v+1/u=1/f

1/v=1/f-1/u

1/v=1/15-1/-10

1/v=2+3/30

1/v=5/30

1/v=1/6

v=6cm

Hope it helps
