To solve the problem step by step, we will follow these steps: ### Step 1: Identify the given values - Radius of the circular plate (r) = 2 cm - Distance of the plate from the mirror (u) = -22 cm (negative because it is in front of the mirror) - Focal length of the concave mirror (f) = -10 cm (negative for concave mirrors) ### Step 2: Use the mirror formula to find the image distance (v) ...
