Part A

Through what potential difference $V$ must electrons be accelerated $($from rest$)$ so that they will have the same wavelength as an x $-$ray of wavelength $0\mathrm{.}155$ nm $?$

Use $6\mathrm{.}626{10}^{-34}{J}^{\text{'}}*s$ for Planck's constant, $9\mathrm{.}109{10}^{-31}kg$ for the mass of an electron, and $1\mathrm{.}602{10}^{-19}C$ for the charge on an electron. Express your answer using three significant figures.
