### Problem 19
**Determine the magnitude and direction of the electric force on an electron in a uniform electric field of strength 2460 N/C that points due east.**

**Explanation:**

The text above asks to determine the magnitude and direction of the electric force on an electron when subjected to a uniform electric field. The specified electric field has a strength of \(2460 \, \text{N/C}\) and is directed due east.

**Solution Outline:**

1. **Electric Force Formula:**
   The electric force (F) experienced by a charge (q) in an electric field (E) is given by:
   \[
   F = qE
   \]

2. **Electric Charge of an Electron:**
   The charge of an electron is \( -1.6 \times 10^{-19} \, \text{C} \).

3. **Calculation:**
   Since the electric field points east and the electron has a negative charge, the direction of the force on the electron will be opposite to the direction of the electric field.

4. **Magnitude:**
   \[
   F = (-1.6 \times 10^{-19} \, \text{C}) \times (2460 \, \text{N/C})
   \]
   \[
   F = -3.936 \times 10^{-16} \, \text{N}
   \]
   The magnitude of the force is \(3.936 \times 10^{-16} \, \text{N}\).

5. **Direction:**
   The force will be directed due west because the electron is negatively charged and the electric field points due east.

**Summary:**

The magnitude of the electric force on the electron is \(3.936 \times 10^{-16} \, \text{N}\), and the direction of the force is due west.
