# Two point charges, one with charge \(+q\) and the other with charge \(-q\), are held fixed at a separation distance \(d\) in a vacuum. What is the magnitude of the net electric field at point \(P\), located at the midpoint of the line segment connecting the two charges?

Two point charges, one with charge \(+q\) and the other with charge \(-q\), are held fixed at a separation distance \(d\) in a vacuum. What is the magnitude of the net electric field at point \(P\), located at the midpoint of the line segment connecting the two charges?

![Two small spherical point charges lie along a horizontal dashed line. The left sphere is labeled +q and the right sphere is labeled -q. A horizontal double-headed arrow below the charges indicates a total separation distance d. Point P is marked with a filled circle midway between the two charges on the line segment. No other labels or axes appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1785830544-jQMAkT.jpg)

- **A.** \(\dfrac{2q}{\pi \varepsilon_0 d^2}\)
- **B.** \(\dfrac{q}{\pi \varepsilon_0 d^2}\)
- **C.** \(\dfrac{q}{2\pi \varepsilon_0 d^2}\)
- **D.** 0
