Above figure illustrates the ray diagram for the formation of image by a concave mirror. The position of the object is beyond the center of curvature of the concave mirror. On the basis of given diagram answer the following questions.
If the size of the object in the given figure is 5 cm and the magnification produced is -0.5. The size of the image is (in cm) ______

A

`-2.5`

B

`-0.1`

C

`2.5`

D

`0.1`

Text Solution

Verified by Experts

The correct Answer is:
C
As we know, magnification,
`m = h_2/h_1`
`h_2=(-0.5xx5)/10`
`h_2 = -0.5 xx 5 `
`h_2 = -0.5xx5`
`h_2 =-2.5 cm`
