AI Generated Solution

To solve the problem, we will use the lens formula and the definition of power of a lens. Here’s the step-by-step solution: ### Step 1: Identify the given values - Object distance (u) = -60 cm (negative because the object is on the left side of the lens) - Image distance (v) = +20 cm (positive because the real image is formed on the right side of the lens) ### Step 2: Use the lens formula The lens formula is given by: ...
