Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.

Question

**Physics Problem: Electron Dynamics in an Electric Field**

---

### Problem Statement:
An electron travels at a speed of \(2.58 \times 10^4 \) km/s parallel to an electric field of magnitude \(1.20 \times 10^4 \) N/C. What distance will the electron travel before coming to a stop?

### Multiple Choice Options:
- \(11.5 \, \text{cm}\)
- \(14.0 \, \text{cm}\)
- \(31.6 \, \text{cm}\)
- \(15.8 \, \text{cm}\)
- \(23.0 \, \text{cm}\)

**Explanation:**
In this problem, you are required to determine the distance an electron will travel before it comes to a stop when it is subjected to a specific electric field.

---

To solve this, consider the following key concepts:
1. **Kinematics and Dynamics of Electrons in an Electric Field:**
- The electron will experience a constant deceleration due to the electric field.
- The force acting on the electron can be calculated using Coulomb's law: \( F = q \times E \)
2. **Kinetic Equations:**
- You can use the equations of motion to find the distance traveled by the electron under constant deceleration until its velocity becomes zero.

**Note to Students:** Be sure to convert units appropriately (e.g., from km/s to m/s) and understand the relationship between the distance, electric field strength, and electron charge.
