Imagine that there is a very very sharp needle, the sharpest in the world. it is so fine and pointy that if you touch it, it will pierce the skin. If you look at it under a microscope, will the ultra sharp needle appear to be flat or still sharp?

It depend on your microscope's magnification and on your needle's sharpness!

It would appear just as flat as it does under a magnifying glass when looking with one eye closed. It will look less flat in a binocular microscope. It doesn't take a sharp needle to pierce skin. The probe in an atomic force microscope has a radius of curvature measured in nanometers, so the tip is only hundreds of atoms. It's not easy to manufacture a smooth surface that small.

depends on your size if you are bigger than that needle so it will appear round ,but if you are smaller than it so it would be flat.
