an object of 5cm height is placed at a distance of 20cm in front of a convex mirror of radius of curvature 30cm. find the position of image its nature and size

u = - 20 cm
ho = 5 cm
R = + 30 cm ... (convex mirror)
The image is formed at a distance of 8.57 cm behind the convex mirror. Thus, it is virtual and erect.
![m space equals space minus space v over u space space
m space equals negative space space fraction numerator 8.75 over denominator negative space 20 end fraction space equals space 0.4 space
A l s o comma
m space equals space h subscript i over h subscript o space
0.4 space equals h subscript i over 5 space
h subscript i space end subscript space equals space 0.4 space cross times space 5 space equals space 2 space c m](https://images.topperlearning.com/topper/tinymce/cache/544fe8e2c50ac37c5368ac40a12dd0be.png)
Thus, the height of an image is 2 cm.
Thus, we can say that tha image is diminished.
