In the figure the four particles form a square of edge length a = 5.60 cm and have charges q₁ = 9.22 nC, q₂ = -21.8 nC, q₃ = 21.8 nC, and q₄ = -9.22 nC. What is the magnitude of the net electric field produced by the particles at the square's center?

One year ago, you bought a put option on 500,000 euros with an expiration date of one year. You paid a premium on the put option of $.03 per unit. The exercise price was $1.30. Assume that one year ago, the spot rate of the euro was $1.29, the one-year forward rate exhibited a discount of 3%, and the one-year futures price was the same as the one-year forward rate. From one year ago to today, the euro depreciated against the dollar by 2 percent. Today the put option will be exercised (if it is feasible for the buyer to do so).

a. Determine the total dollar amount of your profit or loss from your position in the put option.

b.Now assume that instead of taking a position in the put option one year ago, you sold a futures contract on 500,000 euros with a settlement date of one year. Determine the total dollar amount of your profit or loss.

1. Answer the following questions concerning covered and uncovered interest rate differentials and parity conditions:

a. Suppose the spot dollar-euro exchange rate is $1.20/€ , and the 60-day forward rate is $1.24/€. Is the euro selling at a forward discount or premium? What about the dollar?

b. Now suppose the interest rates on one-year U.S. and Eurozone (EMU) bonds are rUS = 5% and rEMU = 3%. You expect that, one year from now, the dollar-euro exchange rate will be at $1.26/€. Today the rate is $1.20/€.  Which should you invest in, the U.S. or EMU bond? Explain Hint use uncovered interest rate parity to get your answer.

c. Suppose the interest rate is 4% in the US and 8% in the UK.  If the actual exchange rate is e = $2.00/£1 (home is the US), what must the expected exchange rate e^e be?

Q:Write a Java application which allows the user to enter student information

The user will enter full name, address, city, province, postal code, phone number and email in text field controls. The student’s major (Computer Science or Business) will be selected from two radio buttons.
A combo box will display the list of courses for each program whenever the user selects the desired program.
A course will be added to a list box whenever the user selects a course from the corresponding combo box. Make sure that the user cannot add a course several times.
Additional information about the student will be provided from a group of check boxes (such as involvement in various activities, etc).
All the information about the student will be displayed in a text area component. Use simple SWING layout managers, such as FlowLayout, BorderLayout, and GridLayout to create the SWING GUI of this application. Provide the titles for the data that will be displayed in the text area.

Note:I know how to do most of the things from question but i do not know how to implement layouts.
