To determine the nature and power of the lens required to rectify the hypermetropic defect for a person whose near point is at 75 cm, we can follow these steps: ### Step 1: Understand the Problem A hypermetropic person has a near point (the closest distance at which they can see clearly) at 75 cm, while the normal near point is at 25 cm. This means that the person cannot see objects clearly that are closer than 75 cm. ### Step 2: Use the Lens Formula The lens formula is given by: \[ ...
