WebUnderstand. In this problem, you are asked to relate motion (the pith ball is at rest, 150 from vertical) to force (it is deflected when in the presence of an electric field). Force and … WebIn an electroscope made by two pith balls, the Coulomb force can be determined by the mass of the pit ball and the distance between the balls. Fig. 1 below demonstrates the setup and the free-body diagram for the force analysis. Fig. 1 On the left is the schematics of the experimental setup. The strings should join at the origin of a protractor so
WebMar 2, 2024 · This means that as the distance between two positively charged pith balls increases, the electrical force between them decreases. Therefore, the electrical charge on each pith ball is not affected by the distance between them. The charge on each pith ball will remain the same regardless of the distance between them.
