A candle of height 6 cm is placed at 2cm distance from the pinhole camera. If the width of the camera is 4 cm, find the magnification and size of the image.

A

14 cm

B

12 cm

C

10 cm

D

9 cm

Text Solution

Verified by Experts

The correct Answer is:
B
Given that size of object, (o)=6cm
Distance of object, (u) =2 cm
Distance of image, (v) = 4 cm
We know, `m=(i)/(o)=(v)/(u)`
`:.` magnification `(m)=(v)/(u)=(4)/(2)=2`
`m=(i)/(o)'i=o""xxm,:."image size,"i=6xx2=12cm`
