Minimum electron energy to resolve 10 pm features

[DeadxBunny]

Homework Statement

The highest achievable resolving power of a microscope is limited only by the wavelength used; that is, the smallest item that can be distinguished has dimensions about equal to the wavelength. Suppose one wishes to "see" inside an atom. Assuming the atom to have a diameter of 100 pm, this means that one must be able to resolve a width of, say, 10 pm. If an electron microscope is used, what minimum electron energy is required?

Homework Equations

I don't know.

How about the de Broglie wavelength?

The electron is charged. What happens to charged particle in an electric field (which has an associated potential difference)?
