Gauss's Law Problem 5

Start Animation 1 Start Animation 2 Start Animation 3 Start Animation 4

Description

A test charge starts at rest and is attracted to a fixed negative charge distribution that has a small (assume it is infinitesimally thin) tunnel that allows the test charge to pass through as shown in the animation (position is in charge radii and time is in seconds). 

Question

If the charge is uniformly distributed, which of the animations correctly depicts the motion of the test charge?
