Question

1 of 20 A negatively charged particle moves through various electric fields. Which of the following correctly indicates whether the negatively charged particle gained or lost energy in each of the following examples? Example 1 Example 2 Example3 Gained energy Gained energy Lost energy Lost energy lost energy gained energy lost energy gained energy gained energy lost energy lost energy gained energy 2 of 20 Based on the equipotentials shown in the example below, order the magnitude of the potentials at points A, B, and C (from greatest to least). 10V >B> C B>A> C > C> B O A O A

Explanation / Answer

1. Gained energy Lost energy Gained energy

2. A > B> C

3. V = kq/r

= (9 * 10^9) * (2* 10^-9)/ 0.707 = 25.4 V
