How Much Energy is Needed for Electrons to Probe Nuclear Size?

[Reshma]

I am quite clueless over this.

Calculate what energy needs to be given to electrons so that they are able to probe the nuclear size.

Is the radius of the nucleus (~1Fermi) relevant in this problem? Help needed..

Your guess is right. For example x-rays can be used to probe the structure of solids because their wavelengthsm are of the same order of magnitude than atomic spacings in solids.

Thanks again for replying!
So, I have to take the de Broglie wavelength as 10^-15m and substitute in $\lambda = \frac{h}{\sqrt{2mE}}$ and obtain the KE, right?

You should check wether relativistic corrections are necessary or not.
