1. Suppose 4 equal positive charges +Q are arranged in a square as shown in the attached diagram. An "x" marks positions A, B, and C. Draw arrows showing the direction of the electric field at each of those points. (If the field strength is zero at a point, say so.)

2. Now we have 4 charges of equal magnitude, but 2 are positive and two are negative, arranged as shown. Find the direction of the electric field at point A (center of the square), and at point B. Show the direction with a arrows whose tails are each point.

3. Again we have 4 charges of equal magnitude, 2 positive and 2 negative. Find the direction of the electric field at points A and B. Indicate the direction with an arrow originating at each point. (If the field strength is zero, indicate this.)

4. As in the first problem, we have four positive charges of equal magnitude. Point A lies between two of the charges. If we call the length of one side of the square L, then point B lies a distance L from point A. (a) Draw arrows to show the direction of the field at each point. (b) At which point, A or B, is the electric field stronger? Support your answer with a well-reasoned argument. (You really don't have to do any calculations, but it is possible to argue without doubt that one is stronger than the other.)

Please help with the following problems.

Please show all work and diagrams plus equations used to solve problem. Thanks!
1) Experimentor A uses a test charge qsub0 and experimentor B uses a test charge 2qsub0 to measure an electricfield produced by stationary charges. A finds a field that is:
ans: The same as the field around B - WHY?
2) An isolated point

The electricfield is defined as the electrostatic force divided by the charge experiencing this force. The Earth's electricfield is directed radially inward and is about 150 N/C at the Earth's surface. This arises because in a region of the atmosphere known as the ionosphere, parts of the spectrum of the radiation from the sun

Three charges are placed on the x and y axes as follows:+2q at the origin (0,0); -q at (a,0); +q at (0,a). Find the magnitude and direction of the electricfield at the point (a/2,a/2), mid-way between the +q and -q charges.

ElectricField
Four identical point charges (q = + 10.0 micro coulomb) are located on the corners of a rectangle. The dimensions of the rectangle are L = 60.0 cm and W = 15.0 cm. Calculate the magnitude and direction of the resultant electric force exerted on the charge at the lower left corner by the other three charges.

Three point charges are located along the circle of radius. Derive the expression for the electricfield in the center.
