To solve the problem step by step, we will follow the concepts of optics related to mirrors, specifically convex mirrors and plane mirrors. ### Step 1: Identify the given values - Object distance (u) = -60 cm (negative because it is in front of the mirror) - Focal length (F) of the convex mirror = +20 cm (positive for convex mirrors) ### Step 2: Use the mirror formula The mirror formula is given by: ...
