A 4 cm tall object is placed on the principal axis of a convex lens. The distance of the
object from the optical centre of the lens 12 cm and its sharp image is formed at a
distance of 24 cm from it on a screen on the lens, in the which ways (towards the lens or away from the lens) will he have to move the screen to get a sharp image of the object on it again? How will the magnification of the image be affected ? .

To solve the problem step by step, we will follow these steps: ### Step 1: Identify the given values - Height of the object (h) = 4 cm - Object distance (u) = -12 cm (negative because it is measured against the direction of the incident light) - Image distance (v) = 24 cm (positive because it is measured in the direction of the outgoing light) ### Step 2: Use the lens formula ...
