A regular hexagon oriented with horizontal top and bottom edges. Five of the six vertices feature identical solid black circular dots, each labeled with the text +q positioned just outside the perimeter. The top-right vertex is an open dashed circle indicating an empty position. At the geometric center of the hexagon is a small central point labeled O. A thin dashed straight line segment connects the center point O to the bottom-left vertex, with a lowercase d beside it to indicate the distance from the center to a vertex. No other labels, lines, text, or axes appear.
Five charges fixed at vertices of a regular hexagon.
Five identical point charges, each with charge \(q = +3.0 \text{ }\mu\text{C}\), are held fixed at five of the six vertices of a regular hexagon in a vacuum. The distance from each vertex to the center of the hexagon is \(d = 0.30 \text{ m}\). What is the magnitude of the net electric field at the center of the hexagon?
