A Coulomb/Electrostatic Force apparatus, which gives very precise results (although not 100% accurate), yielded the data listed below. The apparatus uses two round plates with a diameter of 21.0cm and a plate-separation of 2.50mm. Your voltage vs. force data are.. (Voltage in kv, Force in N) = (1.5, 0.0491), (2.5, 0.1365), (3.5, 0.2676).(4.5, 0.4423) (5.5, 0.6608). What is your value for the permittivity of free space? (You do not need to graph these data.) Given the accepted value of £5 = 8.85x10-12C2/(N m²), what is your percent error?
