Feel Free to give tips or answers to any or all of these questions
1. Two Point charges qa and qb are located on the x- axis at x=a and x=b on the graph of E the x-component of E.
a) What are the signs of qa and qb?
b)What is the ratio of|qa/qb|?
c) Draw a graph of V as a function of x?
Look at relevant equations for graph description
1. The graph is the x- axis qa and qb are located apart on the axis between them is a parabola shape on the positive side and on the lef of qa is an exponential shape in the negative and the same thing on the right of qb
Not sure but about the electric field is positive between the charges and negative on the outsides of the charges
Three Electrons form an equilateral Triangle. 1 nm on each side. A proton is at the center of the triangle. What is the potential energy of this group of charges?

Two ten centimeter diameter electrodes 0.5 cm apart from a parallel plate capacitor. the electrodes are connected by metal wires to a 15V battery. What are the charges on each electrode, the electric field strength inside the capacitor and potential difference between the electrodes when:
a) While the capacitor is attached to the battery?
b)After insulating handles are used to pull the electrodes 1.0 cm apart. The electrodes remain connected to the battery during this process?
c)After the original electrodes are expanded till they are 20 cm in diameter while remaining connected to the battery?
not sure
In a Graph of Ex(described in equations section) the potential at the origin is -50V what is the potential at x=3
graph is a horizontal line from x=0 to x=2 at y=200V/m it the descends at a decreasing slope to zero between x=2 to x=3 to equal zero on x=3.
