A slanted object A B is placed on one side of convex lens as shown in the diagram. The image is formed on the opposite side. Angle made by the image with principal axis is:

Step-by-step solution

Location of image of A :- aligned & 1 v - 1 u = 1 f 1 v - 1 -30 = 1 20 1 v = 1 60 v =60 ~cm & ~m =2 aligned Since size of object is small wrt the location hence aligned & d v=m^2 d u d v=4 1=4 ~cm & h_i=m h₀ h_i(d y)=2 2=4 ~cm aligned Angle made with principle axis =-45^
