Sample Problems with Potential Fields

You need a Java-capable browser such as Netscape 2 for Windows or Netscape 3 for Macintosh to be able to work with these problems. Solve the problem and enter your solution using the scrollbars. The scrollbar values designate the direction of the initial trajectory of the test electron. The equipotentials are indicated by color (cyan is most negative, green is less negative, red is positive and yellow is most positive). Please be patient; it takes a few seconds to set up a new problem.
