# Three point charges are fixed at three corners of a square of side length \(d\), as shown. The top-left corner has charge \(+q\), the top-right corner has charge \(-q\), and the bottom-right corner has charge \(+q\). Point \(P\) is located at the unoccupied bottom-left corner of the square. Which of the following best represents the direction of the net electric field at point \(P\)?

Three point charges are fixed at three corners of a square of side length \(d\), as shown. The top-left corner has charge \(+q\), the top-right corner has charge \(-q\), and the bottom-right corner has charge \(+q\). Point \(P\) is located at the unoccupied bottom-left corner of the square. Which of the following best represents the direction of the net electric field at point \(P\)?

![A square outline with side length d on a white background. At the top-left vertex, a small circle contains a plus sign and is labeled +q. At the top-right vertex, a small circle contains a minus sign and is labeled -q. At the bottom-right vertex, a small circle contains a plus sign and is labeled +q. At the bottom-left vertex, a small solid black dot is labeled P. Dashed light-gray lines connect diagonally opposite corners of the square, intersecting at a central point labeled C. No other labels, lines, text, or axes appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1785830561-TJANWY.jpg)

- **A.** Diagonally up and to the right (toward the center of the square)
- **B.** Vertically downward
- **C.** Horizontally to the left
- **D.** Diagonally down and to the left (away from the center of the square)
