Q5 of 50 Page 43

An object on place perpendicular to the principle axis of a convex lens having focal length 10cm.The distance of an object from the lens is 15 cm. Find the position of an image.

According to the question;

Focal length (f) = + 10 cm


Object distance (u) = - 15 cm.


Image distance = v.


By lens formula;



⇒


⇒


⇒


⇒ V = 30 cm.


Hence image is formed at distance of 30 cm from the lens.
