You can adjust the magnitude of each charge and the location of charge 1 by dragging it back and forth. The charges and distance measurements are recorded in the table when you press Store Result.
Charge 1: Q1 = +μC Charge 2: Q2 = +μC Spring: k = N/m
Results: r = m d = m
r (m) | Q1 (μC) | Q2 (μC) | d (m) |
