please tell me answer​

Answer 1

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
