Question 8 The drawing shows a cross-sectional view of two spherical equipotential surfaces and two electric field lines that are perpendicular to these surfaces. When an electron moves from point A to point B (against the electric field), the electric force does +3.2 x 10-19 J of work. What are the electric potential differences (a) VB- VA, (b) VC - VB, and (c) VC - VA?
a)
VB-VA =-dU/q =-(3.2*10-19)/(-1.6*10-19) =2 V
b)
VC-VB =0 V (since B and C are at same potential)
c)
VC-VA=-dU/q =-(3.2*10-19)/(-1.6*10-19) =2 V
