AP Physics 2hardmcq1 pt
An electron moves from a region of −100 V to −50 V. Its potential energy
A.increases
B.decreases
C.stays constant
D.becomes zero
Explanation
Core Concept
ΔU = qΔV = (−e)(+50 V) is negative, so the electron's potential energy decreases as it moves toward higher potential.
Correct Answer
Bdecreases
