u = -15 cm 
f  =-10 cm 
This means that object is placed between centre of curvature and focus. 
Thus, 
We know, when the object is placed between the centre of curvature and focus of concave mirror the image formed is real, inverted and magnified

CASE STUDY : Light is a form of energy which induced sensation of vision to our eyes. It becomes visible when it bounces off on surface and hits our eyes. Regular reflection takes place through a smooth polished surface. The mirror outside the driver side of the vehicle is usually a spherical mirror and printed on such mirror is usually the warning "Vehicles in this mirror are closer than they appear". (i) What is the reason for this warning written on the mirror ? (ii) Draw a ray diagram showing the image formation in such kind of mirror. (iii) State two positions in which a concave mirror produces a magnified image of a given object. (iv) How is linear magnification it related to object distance and image distance ?

It is desired to obtain an erect image of an object, using concave mirror of focal length of 15 cm. Where should we place the object? Where will the image of this object be, if it is placed at 30 cm in front of the mirror? Draw a ray diagram for this situation also to justify your answer.
