Consider two points in an electric field. The potential at point $1,$ V$1,$ is $31$ V$.$ The potential at point $2,$ V$2,$ is $186$ V$.$ A proton is moved from point $1$ to point $2.$

(a) Write an equation for the change of electric potential energy $.$

$$$($b$)$  Solve for the numerical value of the change of the electric potential energy in electron volts $($eV$).$  

 

 $($c$)$  How much work is done by the electric force during the motion of the proton in J$?$
