How much work does the electric field do in moving a protonfrom a potential of 1

Question

How much work does the electric field do in moving a protonfrom a potential of 121V to a point where it is -52V? Express ans.in joules and electron volts. I got the answer in J=2.77*10-17 But, I need to know how to get it in the electron volts...Iknow the answer is 173eV. Please show me how to work it out. Thanksfor your time. Will Rate.

Explanation / Answer

You just need a simple conversion factor. Your answer should be injoules initially, and the best way to solve for eV is just toconvert your answer. 1 joule = 6.24150974 ×1018 electron volts(Just got that from google). The joule unitscancel out leaving you with eV: 2.77x10-17J(6.24150974x1018eV/1J) = 172.89 eV or about 173 eV
