Charge two strips of tape in the same manner as before, making sure to make them the same length (if you want to reuse the strip of tape from before, ground the charge on the tape first by passing your hand over the tape). In the first part of the experiment, we will vary the distance r while holding the charges q1 . . and q If you make a mistake or want to start over, either create a new analysis object or delete the marks you made. This lab experiment's goal was to observe and ascertain how the electrostatic force between two, charged, conducting spheres changes depending on their proximity to one another and the charge applied to, them. G=6.67 Finally, note that Coulomb measured the distance between the spheres from the centers of each sphere. C, how far apart are the ink drops? where At one end of the rod is the metallic sphere A. objects that occur due to the effect of gravity. The top sphere will be re-positioned, gradually decreasing the sphere separation. The PASCO Coulombs factor balance: Draw arrows between each of the stages in Figures 4 and 5. Closely observe the flat oral surface. Descriptions of the major components of apparatus for this lab are now given. An unknown amount of charge would distribute evenly between spheres A and B, which would then repel each other, because like charges repel. Using this technique, he measured the force between spheres A and B when they were charged with different amounts of charge. From outside a uniform spherical distribution of charge, it can be treated as if all the charge were located at the center of the sphere. charged rod. 2 Some types of social behaviors are emotional, Spectroscopy studies the interaction between light and matter. The first unknown is the force (which we call Bring the charged rod to about cm away from the sphere but do not touch them, together. f) Use your measurement of to determine the repulsive electrostatic force using Equation 3 for each separation distance. Yet, of course the surface can also assume a new translational symmetry by which, in a diffraction experiment, as, for example, using low-energy electrons . ); and (ii) only one type of mass exists, whereas two types of electric charge exist. Coulomb's law predicts that two objects with the same charge will have a repulsive force between them. )FertilizationQuestion 12. This will be split into two parts; first measuring the the force as a function of distance, and second we will look at how the magnitude and sign of the charges affect the force. average angle value, . or 130 microns (about one-tenth of a millimeter).
