In Fig. 24-61 a , we move an electron from an infinite distance to a point at distance R — 8.00 cm from a tiny charged ball. The move requires work W = 2.16 × 10 -13 J by us. (a) What is the charge Q on the ball? In Fig 24-6l b , the ball has been sliced up and the slices spread out so that an equal amount of charge is at the hour positions on a circular clock face of radius R = 8.00 cm. Now the electron is brought from an infinite distance to the center of the circle, (b) With that addition of the electron to the system of 12 charged particles, what is the change in the electric potential energy of the system?

Lab-Based Section
Use the following information to answer the lab based scenario.
A student performed an experiment in an attempt to determine the index of refraction of glass.
The student used a laser and a protractor to measure a variety of angles of incidence and
refraction through a semi-circular glass prism. The design of the experiment and the student's

2a) By hand (i.e., without using computer software), create a linear graph on graph paper
using the student's data. Note: You will have to manipulate the data in order to achieve a
linear function.
2b) Graphically determine the index of refraction of the semi-circular glass prism, rounding your
answer to the nearest hundredth.
