Question

1. Two vericle parallel metal plates are connected to the terminals of a 7.80 V power supply, creating an electric field with magnitude 1280 V/m and directed upward.

1a) what is the separation between the plateas?

1b) A -4.90 uC charge is placed between the plates. what is the magnitude and direction of the force this charge experiences?

2. Suppose that four equal magnitude charges are located at the corners of a square, as show in figure. Point E is at the midpoint of the bottom side of the square.

2a) sketch and lable arrows showing the direction of the electric field due to each charge at point E

2b) Sketch and label an arrow showing the direction of the net electric field at point E?

3. Three point charges (qA = -5.30 uC, qB = 2.15 uC, qC = -3.45 uC) are placed along the +x-axis as shown.

3a) label the diagram with arrows showing the directions of Fb to a and Fc to a.

3b) what is the magnitude and direction of the netforce on qA due to qB and qC?

3c) what is the magnitude and direction of the electric field at the location of qA?
