Use the equation 2 , to determine [:0 using the slope of the graph. q To perform this experiment, we tied a piece of string to the end of two balloons and, charged each balloon by rubbing it approximately ten times against our hair. Want to cite, share, or modify this book? The force as a function of the distance between the charges Note that the lecturer uses d for the distance between the center of the particles instead of r. True or falseIf one particle carries a positive charge and another carries a negative charge, then the force between them is attractive. Two charges are repelled by a force of 2.0 N. If the distance between them triples, what is the force between the charges? 4cm and 3cm while the charge remains the same. If we double the distance between the objects, then the force between them decreases by a factor of q The pith ball electroscope in Figure 1b, for example, shows the attraction 1 produced to identify relationship between the charges and force.

The spheres, can readily be charged because they are constructed of conductive material and can be powered by a strong, and reliable kilovolt source. [BL][OL]Discuss how Coulomb described this law long after Newton described the law of universal gravitation. r where is the electrostatic repulsive force between the spheres, and is the weight of the suspended sphere. Physics Lab report Aammar Paracha Section MX Feb 6th 2015 OPTICS Abstract: This experiment revolves around using light rays and lenses. We wanted to see how much charge and how many electrons were transferred. This device, shown in Figure 18.15, contains an insulating rod that is hanging by a thread inside a glass-walled enclosure. First a simply observation was made of the electrical forces on two pieces of tape taking note of their attraction and repulsion. The sphere is 1.2 cm in diameter. He did not explain this assumption in his original papers, but it turns out to be valid.
