Transcribed Image Text:The image illustrates a geometrical arrangement involving two point charges and a point labeled "P".
- There are two charges shown: \( q_1 \) and \( q_2 \).
- \( q_1 \) is a positive charge, represented by a red sphere with a plus sign.
- \( q_2 \) is a negative charge, represented by a blue sphere with a minus sign.
- These charges are placed at either end of a horizontal line segment. The distance between \( q_1 \) and \( q_2 \) is labeled as \( d \).
- Above the midpoint of the line segment connecting \( q_1 \) and \( q_2 \), there is a point labeled "P".
- The point \( P \) is equidistant from both charges, and the distance from each charge to point \( P \) is also labeled \( d \), forming an equilateral triangle.
This configuration is useful in problems involving electric fields or potentials, where the point \( P \) is often a location of interest for calculating these quantities.
