(Answered) An electron microscope is using anbsp10 kev electron beam

Academics

An electron microscope is using a 1.0 keV electron beam. An atom has a diameter of about 10^-10 meters.

Suppose we replace the electron beam with a proton beam. What proton energy is needed to achieve the same resolution as the electron beam in Part A?

Express your answer in electron volts to three significant digits.
