Two negatively-charged balloons with a mass of 1.78 g are suspended by threads from a common point on the ceiling. Just like mass, electric charge is a fundamental property of matter, and so it is important to understand how exactly this impacts the corresponding . Sm8 21 . Two identical small spheres of mass 2.0g are fastened to the ends of an insulating thread of length 0.60m The spheres are suspended by a hook in the ceiling from the centre of the thread. The distance between them is x and angle between the threads (2= 10). A pith ball is a very small, lightweight object that picks up electric charge quite well.
