Question
**Point Charges Problem**

**Given:**
- Point charges \( q_1 = 55 \, \mu C \) and \( q_2 = -40 \, \mu C \) are placed 0.8 m apart.

**Questions:**

a. What is the force on a third charge \( q_3 = 15 \, \mu C \) placed midway between \( q_1 \) and \( q_2 \)?

- **Force on \( q_3 \)** is **12.656 N**, in the **direction toward \( q_2 \)**.

b. Where can \( q_3 \) be placed so that the net force on it is zero?

- If \( q_3 \) is placed **near \( q_2 \) directly opposite from \( q_1 \)**, at a distance of **0.4319 m** from \( q_1 \), the net force on it will be zero.
