Transcribed Image Text:### Calculating Work to Set Up Four-Charge Configuration
#### Problem Statement:
How much work is required to set up the four-charge configuration of the figure if \( q = 2.43 \, \text{pC} \), \( a = 77.2 \, \text{cm} \), and the particles are initially infinitely far apart and at rest?
#### Diagram Explanation:
The diagram depicts a square configuration with the following placements of charges at the vertices:
- Top-left corner: \(\ +q\)
- Top-right corner: \(\ -q\)
- Bottom-left corner: \(\ -q \)
- Bottom-right corner: \(\ +q\)
Each side of the square is denoted by \( \ a \) and measures 77.2 cm.
#### Input Fields:
- **Number**: an input field where the calculated work value will be entered.
- **Units**: a dropdown menu to select the unit for work, default set to Joules (J).
#### Goal:
Determine the work needed to assemble this four-charge configuration given the specified conditions.
