Question

For an object placed at a distance of 20 cm from the pole of a mirror, an image is formed 40 cm
farther from the object on the same side.
c) What is the nature of the mirror ? Give reason for your answer.
b) Is the image formed real or virtual ? Give reason for your answer.
c) Calculate the focal length of the mirror used.
) Draw a ray diagram to show the image formed.​

So, it,s ans mean m is equal to -2 cm and nature of image is real and inverted

The focal length will be -40/3
