Part C: The effect of the amount of charge and the force of electrostatics 3 pith balls of identical size and mass are used in an experiment to investigate the effect of changing the product of charges in a system on the electrostatic force. A hanging Pith ball is charged by conduction with a charged pith ball on a wand so that each initial has the same charge. The charged wand pith ball is then placed at the designated radius. The electrostatic force has been analyzed from the angle of deflection of the hanging pith ball. To charge the charge on the hanging pith ball a neutral pith ball on a wand is touched with the hanging ball. They share charge thus the hanging pith ball now has half the original charge. The results were as follows: Table 2: The electrostatic force as function of the product of charges. Charge on the wand pith ball, q Relative charge on Product of the the suspended pith charges, 9192 Force between the charges, Fa, (N) ball, qz 1 1 1 0.320 1 /2 /2 0.160 1 4 1/4 0.080 1 1/8 1/8 0.040 1 1/16 1/16 0.020 Using graphical analysis techniques confirm that these results support Coulomb's Law. Be sure to describe Coulomb's law and the expected graphical relationship Using the data find a meaningful Mathematical relationship between Force and Charge and discuss the meaning of the slope
