K.C.S.E Physics Q & A - MODEL 2008PP2QN05

​The diagram in figure 2 shows an object O placed in front of a converging lens. F and F are the principal foci for the lens.

The object is now moved along the principal axis until a virtual image is produced.
On the same diagram:
(i) Draw the object O in the new position along the principal axis;
(ii) Sketch rays to show formation of the virtual image
