Three charged particles are configured in a triangular configuration; see figure 1. The red charges are anchored and each have a charge of 6.0x10 C. A free-floating, 200.0 kg charge of -3.0x10° C is initially motionless. Calculate the final speed, direction and the work done on the free-floating electron after 5.12x10 s elapses. How far did it travel in that time? 2. Next a positively charged 100.0 kg block is held stationary by an anchored ball at the end of a frictionless ramp; see figure 2. Calculate the charge of the block. 3. Explain how an object can be polarized? 4. A 100.0 kg, 3.0x10 C charged object is 3.0 meters from a -2.0x10° C charged object that is anchor in place. A neutrally charged object is then placed 3.0 meters on the other side of the 3.0x10 C charged object. Calculate the mass the neutrally charged object needs to be in order to gravitationally attract the 100.0 kg, 3.0x10° C charged object such that it holds it in static equilibrium? 5. What makes a good conductor? Why is the electric field inside a conductor zero?
