Question

2. The following figure has two charged pith balls. Red ball is connect to a spring as shown. when we move blue ball towards the red bad red ball will also move. Take position of the red ball as Xr, Position of the blue ball as Xb, Distance that the spring is compressed as D and separation of the balls as R.

A) What are the things that affect the position of the red ball but do not themselves change as you change the position of the blue ball? (example: the charge of the blue ball).

( hint) There are four things total, and we're expecting you to come up with at least two more of them. Identify each in a phrase. Then state the symbol that you will use to represent each of them in equations to come.

3. Suppose we were to write the distance D in terms of Xr, since D is always positive and Xr is negative, we would have to writ: D= lXrl.

A) Now write the distance R in terms of Xb and Xr.

B)There are 2 horizontal forces acting on the red ball. Identify each force in a phrase where you state what kind of force is acting and what object is producing the force. Remember, both forces must act on the red ball.

C) Write the net force equation for the red ball (you need draw the FBD)
