Background information on field theory: In an electric field theory, a charge affects the space around it, creating a field. Another charge entering this space is affected by that field and experiences a force. In this scenario, the two charges do not directly interact with each other, one charge creates a field and the other charge interacts directly with that field. The direction of the electrical force on a charge is along the direction of the field. Part I: Selecting different charge configurations You will investigate 4 potential charge situations. You can select the magnitude for these charges, but each charge must be whole number of nC (nanocoulombs). ie. 1x10°C or 2x10-°C or 3x10-9 C, etc. The charge configurations are: One positive charge One negative charge 2 like charges (positive or negative) 2 charges of opposite sign Part II: Predict Using your understanding of electric forces and electric fields, draw the electric field lines for all of these configurations. At this point you are not making any calculations, but you are making predictions about how the electric field around the charges will look. Draw the field lines for the isolated charges below.

Explanation & Answer

Hi, here is the completion of your assignment :). Please just message me if you need more assistance :). You can count on me if you have future assignment :)

Electrical lines
Part I: Charge configurations
1. Electric Field
To determine the effect of a charge would be at every point surrounding of it, we need same sort
of reference. That reference is a test charge.
Field map gives the map of electric filed due to a charge. The equation for the force between two
electric charges is:
F =K * Q1 Q2
r2
If we want to work out the effects on any charge, we only have to multiply the vector of the test
charge by the magnitude of the new charge.
If we want to map the field for Q, the we need to know exactly what would hapen if we put Q2 at
every point around Q1. But this obviously on the value of Q2 by convention, we choose
Q2=+1C.
The lecetric filed strength is just the force per unit charge and has the same magnitude and
direction as the force on our test charge.
E =K * Q1
r2
.

. . F =E*Q
2. Positive Charge acting on test charge
As both the charges are postive, they repel each other, we can see that at ever point the positive
test charge would experience a force pushing it away from the carge Q.

3. Negative Charge acting on test charge
The arrows are in the same length because the magnitude of the charge is the same and so is
magnitude of test charge. Thus, the magnitude of the force is the same.

The arrows point in the opposite direction because the charges now have opposite sign and so the
test charge is attracted to the charge.
*Important points to remember about Electronic Point*




There is an Electric Filed at every point in space surrounding charge.
Filed wires are merely a representation
It always start at a right angle...
