Hello friend!
As per the question, the object is placed in front of a concave mirror at a distance of 10cm
The image is erect and is twice the height of the object i.e it has got magnified.
Magnification = - image distance/ object distance
2= -image distance/-10
2×20= image distance
The image distance=20cm.
It means that the image is formed behind the mirror at a distance of 20cm.
