Travis Pollard January 26, 2005 Coulomb's Law Experiment Objectives To prove and investigate Coulomb's |Law of electrostatic attractions and repulsions. Hypothesis I think that as the distance that the two balls are separated becomes greater, that the distance they repel from one another will become less. The reason I feel this way is that the ball will give off the same amount of force to repel the ball that is suspended, but it will be at a farther distance so the force on the hanging ball will be much less. Materials: on lab sheet Procedures: on lab sheet Symbols F - the electrostatic repulsion between the spheres Mg - the weight of the suspended sphere D - the suspended ball's distance from its equilibrium position L - the length of the suspension R - the separation between the two balls (center to center) Experimentation 1st Reading D ( Ball's distance from original position) R (separation between two balls) Distance of ball...
