An object $5 \mathrm{cm}$ high forms a virtual image of $1.25 \mathrm{cm}$ high, when placed in front of a convex mirror at a distance of $24 \mathrm{cm}$. Calculate the position of the image.

An object $5 \mathrm{cm}$ high forms a virtual image of $1.25 \mathrm{cm}$ high, when placed in front of a convex mirror at a distance of $24 \mathrm{cm}$. Calculate the the focal length of the convex mirror.

An object forms a virtual image which is $\raisebox{1ex}{$1$}\!\left/ \!\raisebox{-1ex}{$8$}\right. \mathrm{th}$ of the size of the object. If the object is placed at a distance of $40 \mathrm{cm}$ from the convex mirror. Calculate the position of the image.
