Inducticm Explain how polarization plays a role in charging by induction. Your expla- nation should include: 1. How like and opposite charges interact. 2. How polarization occurs. 3. 1What role a ground plays in the charging process. Electrostatic Force The electrostatic force between two dust particles is 1.0(1U)_5N. If the distance between the two particles doubleJ what is the new force between them? Balanced Forces Two identical charged particles, each with a charge of +5.1] #0, are 2.1] meters apart. In the middle between these two particles. there is a third charge of -1.0 #0. What is the net electrostatic force on the third particle? 1. Make a sketch of the three charges as described. 2. Draw arrows for the forces on the third charge in the middle. Electric Field Lines Explain why electric field lines for a positive source charge are directed outwards and inwards for a negative source. Make a sketch of the electric eld in the region between two separate positively charged and negatively charged spheres
