### Lab I: Charges & Fields**Instructions:**1. **Pull the required charges** to obtain the arrangements shown below (one at a time). Use the superposition principle and: a. **Draw the net electric field** at the position of the E-field sensor. b. **Write an expression** for the net electric field at the position of the E-field sensor (show all your work). c. **Find the magnitude and direction** of the net electric field at the position of the E-field sensor (click on "show numbers" and verify your answers). Note all charges are fixed at the grid, and 1 box = 0.1 m.---**Diagrams Explanation:**1. **First Arrangement:** - The diagram features a grid of yellow squares. - There is a negative charge denoted by a blue circle with a minus sign. - There is a positive charge denoted by a red circle with a plus sign. - An E-field sensor is located at the top, represented by a white circle.2. **Second Arrangement:** - Similar grid setup with yellow squares. - The negative charge (blue) and positive charge (red) are positioned with a white circle (E-field sensor) in the middle.3. **Third Arrangement:** - The same grid setup. - Negative charge on the left, positive charge on the right. - E-field sensor is placed at the bottom, indicated by the white circle.**Note:** Each arrangement is designed to help understand how electric fields are influenced by charges. Calculations should consider both magnitude and direction for accuracy.

Given Pull the required charges to obtain the arrangements, as following below.
