a thin rod of length f/3 is placed along the principal axis of a concave mirror of focal length f such that its image which is a real and elongated just touches one of its end of the rod what is its magnification

An object is placed at a distance of 20cm from a equi-concave lens of focal length 30cm find the position and nature of the image. whose one surface is silvered. If the radius of curvature of the silvered surface is 60cm
