1. Explain the

objectives of Lab_1.

The

first objective of this lab is to determine if the equipotential lines for two-point

charges of equal magnitude, but opposite charges match the theoretical

expectations. The second objective of this lab is to determine what the

equipotential lines look like for a specific placement of point charges. The

third objective for this lab is to determine the electrical field at various

points on a dipole. The fourth objective for this lab is to determine the

electric field intensity for a negative line charge and the electric field

intensity between two oppositely charged line charges. The final objective for

this lab is to analysis a given pattern of equipotential lines.

2. For the

finite line charge in Fig. 1 write an expression for electric field.

3.

What is the relationship between electric field and

potential? For a given potential V=

f(x,y,z) how do you determine the electric field.

The relationship between electric

field and potential is that the electric field is equal to the negative

gradient of the electric potential. You would determine the electric field by deriving

f(x) with respect to x, f(y) with respect to y, and f(z) with respect to z. Then you would add

them together and multiple by negative one.

4.

What is an electric dipole? Write an expression for electric

potential and electric flux density in vacuum for a dipole at far field.

An electric dipole is when two

charged particles with equal magnitude, but opposite charges are separated by a

small distance.

5. Explain

equipotential lines and plot an equipotential line for a point charge.

Equipotential lines are similar contour lines on a map with trace

lines of equal electric potential. Equipotential lines are drawn such that they

are always perpendicular to the electric potential line and movement along

these lines always require zero work.
