Answer the following questions in lab write-up: 1. How does the potential vary with distance on your plots?

2. Calculate the electric field strength at a few places with different characteristics using Eq. 2. Do your results agree with the idea that electric field line density is proportional electric field strength? Sketch neatly and clearly an appropriate amount of lines on your grid paper. You may want to use a different color.

3. Consider the following situation: An object with charge qo = 1.5? C and mass 0.7 g starts from rest at the +6V equipotential line. Calculate its change in potential energy and speed when it reaches the +2V line.
