QUESTION 206

An electron moves from electric potential +80.0 V+80.0\,\mathrm V to +180 V+180\,\mathrm V. Use q=−1.60×10−19 Cq=-1.60\times10^{-19}\,\mathrm C. What is its change in electrical potential energy?
(A)
+1.60×10−17 J+1.60\times10^{-17}\,\mathrm J
(B)
−4.16×10−17 J-4.16\times10^{-17}\,\mathrm J
(C)
+4.16×10−17 J+4.16\times10^{-17}\,\mathrm J
(D)
−1.60×10−17 J-1.60\times10^{-17}\,\mathrm J
