Answer:

Correct option is

A

4 cm, real

According to new cartesian sign convention,

Object distance, u=−15 cm

Focal length of the concave mirror, f=−10 cm

Height of the object, h

0

=2 cm

According to mirror formula,

v

or v=−30 cm

The image is formed at a distance of 30 cm from the mirror on the same side of the object.

It is a real image.

Magnification of the mirror, m=
