USW00094728 The positive charges on the wall will move towards the balloon, while the negative charges will repel against each other. Today we know that Using Coulombs law, we can explore the effect of the distance, between two charged particles, on the force between them. electricity concepts. Bring the lucite rod near (but not touching) the top of the electroscope, so that the electroscope is deflected. Thus, the positive charge is attracted to the rod more strongly than the negative charge is repelled, and there is an overall net attraction. Typically, after charging, the needle might be at 80. Question 2: What do you think will happen when the balloon is moved closer to the wall? The measurements done with the micrometer obtained the highest number of significant figures for the thickness of a single sheet of text book paper. Recharge the metal plate by placing it back on the lucite, touching the lucite, and then lifting the plate off with its insulating handle. Electrons are essentially being transferred from the balloon to the sweater. If the wire or path is subsequently disconnected, the conductor as a whole is left with a net positive charge. Placeq 1 andq 2 4cmapart. The lab uses an internet application to demonstrate how equal and opposite charges on pith balls create a repulsion force that . around a charged body. When rubbed, a piece of amber can attract small objects like tiny pieces of paper.
