2. A charged object called q1 (+100 C) is in the vicinity of a second charged object called q2 (-50 C). Each object has the same mass. These two objects make up a closed system.

a. At what separation distance will they electrostatically attract each other with a force of 1000 N?

b. What minimum amount of charge must be removed from object q1 and placed on object q2 so that they will begin to electrostatically repel each other? Explain your response.

c. What minimum amount of excess charge must be removed from object q2 and placed on object q1 so that they will begin to electrostatically repel each other? Explain your response.

d. Which of these two objects, if either, would exert a larger force on the other object. Explain your response.

e. What amount of mass would these particles have to have in order to make their gravitational attraction match their electrostatic attraction for a separation distance of 10 m?

In object C Define a class called XYPoint that will hold a Cartesian coordinate (x, y), where x and y are integers. Define methods to individually set the x and y coordinates of your new point and retrieve their values. Write an Objective-C program to implement your new class and test it (main section of the file). Your test program needs to create two instances of your class. Make sure your program test prints out the values that you have...
