Coulomb's Law Lab Report By: Khushmeet Sandhu Introduction 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. The Coulomb Balance is a highly sensitive torsion balance made up of two spheres, one of which is, fastened to a counterbalanced rod suspended on a thin torsion wire and the other to a special sliding assembly, that is free to slide along the axis, increasing or decreasing the distance between the two spheres. Key terms Equations Comparing electric force and gravitational force Coulomb's law may look somewhat familiar, because it has a lot in common with Newton's law of gravitation: At one end of the rod is the metallic sphere A. This problem emphasizes the fact that even if we have two different charges, mutual electrostatic force between them will be same. 1 The pith ball electroscope in Figure 1b, for example, shows the attraction However, this structure is much more easily seen in a relative of the sand dollar, an urchin. NOTE: Please use Basic English language/ Common language just like last time. One must rotate the dial, which is coupled to the torsion wire, in the opposite direction of the original, angular displacement in order to return the sphere to its equilibrium position. Then describe the mobility(movement), if any, of the two kinds of cells. f Record your observations. Provide details on what you need help with along with a budget and time limit. What is the force of repulsion between the charges in newtons? Question 6.

Institutional Affiliation: Enlist others in a common vision by appealing to shared aspirations. For the electronic transition from n=2 to n=4 in the hydrogen atom. Note: If you hear a crack or pop sound while the rod is close to the sphere, this means that they were too close to each other and charge jumped across the gap. The order of the steps is critical to success! 8 Compare this value of [3G with CD in the table. . charge on the tape. Although Coulombs law is true in general, it is easiest to apply to spherical objects or to objects that are much smaller than the distance between the objects (in which case, the objects can be approximated as spheres). Then we adjusted the potential voltage of the spheres and measured the resultant force by reading off Also, work carefully from this point: if you touch the charged sphere to anything it will immediately discharge and you will have to charge it again. to establish the relation between force and Skip to document Ask an Expert Sign inRegister Sign inRegister Home Question 18. i respectively.
