1) A negatively charged Teflon (plastic) rod is held near two initially neutral aluminum pie plates that are touching as shown at right. The plates are held using insulating cups. The Teflon rod never touched the pie plates, and no sparks have jumped. Negatively charged Teflon rod a.

As a result of an electron being added to another part of the molecule on the left, the configuration of the three ions (ABC) changes, drawing ion D in a bit closer, as shown in the figure on the right. Without doing the calculation, will the force that (ABC) exerts on D increase, decrease, or remain the same as it was in part 1? Explain your reasoning.

Consider a positive source charge Q, that is being held in
place. A nearby negative test charge q moves from point A to point
B.
a) What is the direction of the electric force that the source
charge exerts on the test charge?
b) As the negative test charge moves from point A to point B,
does the electric force cause it to speed up, slow down, or move at
a constant velocity?
c) As the negative test charge moves...

Help Please! A point charge is place at the origin of a cartesian coordinate system. Another point charge is placed at the coordinates (0, -5.0 m), and a third charge is placed at (7.0 m, 0). If all three particles have a charge of 3.0 μC, find a)the magnitude of the net force on the charge at (0, -5.0 m) b)the direction (measured in degrees from the negative x-axis) of the net force on the charge at (0, -5.0 m)....
