The object is placed at 20 cm in front of the convex mirror and the plane mirror is 12 cm from the plane mirror. The image of the object formed will be virtual. Therefore the image formed will be at positionv=−u=−12. Where u' is the object distance v' is the image distance and f' is the focal distance.
