(8%) Problem 1: Consider two points in an electric eld. The potential at point 1, V1, is 39 V. The potential at point 2, V2, is 152 V. An electron at rest at point 1 is accelerated by the electric eld to point 2. 25% Part (3) Write an equation for the change of electric potential energy AU of the electron in terms of the symbols given' AU=-e(V2-V1) 25% Part (b) Find the numerical value of the change of the electric potential energy in electron volts (eV)l AU= 113 AU = _ll3.0 5' Correct! V Correct! $3 25% Part (c) Express v2, the speed of the electron at point 2, in terms of AU, and the mass of the electron me.
