Question

focal length of a convex mirror is 10 CM an object is kept at 20cm from the pole of the mirror. find the position of image​

Answer 1

Answer:

Image is kept 6.67 cm away from the mirror.

Step-by-step explanation:

Focal length(f)=10cm

Object distance(u)= -20cm

According to mirror formula,

1/f=1/v+1/u

1/10=1/v+1/(-20)

1/10=1/v-1/20

1/10+1/20=1/v

(20+10)/200=1/v

30/200=1/v

v=200/30

v=6.67cm
