1. Electric Potential

For the charge distribution given figure 1, each gridline represents 1 cm and Q = 2* 104 C. A negative test charge q = -5* 10"5 C and m = 12*10-7 kg is then placed at Point P and released. Make a model (system schema, energy bar charts, electric potential lines, word explanation of the motion) and calculate the speed of the test charge when it is 0.1 cm away from the positive charge.

2. Liner Charge Distribution

Consider the charge distribution, shown in figure 2, where a charge of Q = 56 nC is uniformly distributed over a semi-circle of radius r = 2 cm. Construct the integral that gives the exact voltage at Point P, located in the center of the circle. (Note: you do NOT have to solve the integral.) Explain what each quantity represents and what you are doing at each step.
