Question

Equipotential lines for a region are provided below. The lines are separated by 100V increments. Which point has the largest magnitude E-field? Sketch the electric field at each of the labeled points. Estimate the magnitude of the field at Point C. An electron is shot from point A to E with an electron gun. Use a bar chart to explain whether it gains or loses kinetic energy, assuming there are no other forces. Explain and/or show your work for each part. d) A square of 1 cm times 1 cm has charges on 2 corners. Calculate the potential difference between points A and B? Which has the higher (more positive) potential?

Explanation / Answer

d)

VA = VB = kq1/x + kq2/r = (9*10^9*1*10^-9)/(0.01) + (9*10^9*-2*10^-9)/(sqrt2*0.01) = -372.8 V

Both has same potential.

VA - VB = 0 V
