How do you know two different types of charges exist? Please use your observations/evidence to support your reasonin Vector Applications A. B. Y axis Y oxis 7 uC 0.5 m 60 -Xaxis Xaxis -4 pC Three point charges of 2.00 µC, 7.00 µC, and-4.00 uC are located at the corners of an equilateral triangle as shown above in picture A. The two on the x-axis are in fixed positions. 1. In picture B, use trig and vector identities to calculate the x and y components of the displacement vector between the 2.00-uC charge and the 7.00-uC charge. 2. Draw a free-body diagram to show the electric forces exerted on the 7.00-uC charge and clearly indicate which object exerts each electric force on it, and in which direction. (Note: You are not being asked to calculate forces, but simply to draw the proper vectors.)
