To resolve an object in an electron microscope, the wavelength of the electrons must be close to the diameter of the object. What kinetic energy, Ek

Can you provide a detailed calculation of the correct answer please. Thank you!

To resolve an object in an electron microscope, the wavelength of the electrons must be close to the diameter of the object.What kinetic energy, Ek , must the electrons have in order to resolve a protein molecule that is 8.80 nm in diameter? Take themass of an electron to be 9.11 X 10‘31 kg. E1. = 1.87 x10-53 q]
