If a equiconvex lens of focal length f is cut into two halves by a plane perpendicular to the principal axis, then

If a equiconvex lens of focal length f is cut into two halves by a plane perpendicular to the principal axis, then

Focal length of an equiconvex lens is 20 cm. If we cut it once perpendicular to principal axis in and then along principal axis. Then, focal length of each part will be:

An equiconvex lens of glass of focal length 0.1 metre is cut along a plane perpendicular to principle axis into two equal parts. The ratio of focal length of new lenses formes is
