Answer:
Thus the object should be placed at a distance of 30 cm on the left side of the concave lens. Linear magnification, m=vu=-10-30=13.
Here, focal length of concave lens.object distance,image distance,magnification of lens
object distance,image distance,magnification of lens Thus the object should be placed at a distance of 30 cm on the left side of the concave lens. Linear magnification. The positive sign of m shows that the image is virtual and erect, and its size is
