3.) a. Sketch the electric field-lines for the charge distribution shown. 5 pts. b. If you were a long way away (Cleveland? Detroit?). What would the field-lines look like? 3 pts Describe or sketch
2. Electric dipole (20%) A very common charge arrangement in electromagnetics is the dipole. A charge dipole is illustrated in the figure below. In this problem, we will find the potential and field due to a dipole. tq X (a) Find the electrostatic potential at an arbitrary position in spherical coordinates, that is find the potential at the position (r, 0,0). (b) For large values of r, we can write: Z(17 cos 0 + -1/2 ~(1 7. cos 6)-1/2 ~...
An electric dipole consists of a positive charge separated from a negative charge of the same magnitude by a small distance. Which, if any, of the diagrams below best represents the electric field lines around an electric dipole?
Sketch the electric field lines and the surface charge distribution (indicate by + and -) on a metal sphere placed in a uniform electrical field E.
1.4. DRAWING FIELD LINES 3 1.4 Drawing Field Lines 1. Sketch electric field lines for the following four situations: a single positive charge; two positive charges separated by a distance d; a negative and a positive charge separated by a distance di and two negative charges separated by a distance d. For each sketch, assume that all of the charges have the at least 8 equally space field lines same magnitude and use exiting from each charge. Use the circles...
3. A platinum wire of resistance 5 ohms has 4[amperes] of electric current flowing through it. (3a) How many electrons are entering (and leaving) the wire per second, and why? (3b) What is the voltage drop across this wire in Volts? (3c) What is the magnetic field magnitude at a distance of 5[mm] away from the wire
How to solve Part 4c? Sketches of electric field lines and equipotentials Sketch and answer 4 - A through 4 - D in your answer book. Consider different charge configurations as shown: 4 - A : Suppose you are a test charge and you start at some distance from the charge q = +1 below, such as at the point X. Starting at point X, what path could you move along without doing any work? i.e. which Ē. ds is...
1) Coulomb's Law in 1-D (a) For the charge configuration below, sketch the relevant field lines (or lines of force) that a test charge would experience along the 1-D coordinate system. Note: Choose to either draw the field lines or the lines of force, but not both. (4 pts) (b) For the charge configuration below, identify in which region it is possible for a net zero electric field to exist (Region 1, 2, or 3) and mark the approximate position....
2 волеон 1. PBrs Он Electric Field in polar (r and e) form = Magnitude of net field Direction angle of net field e) The force acting on a charge is given by F =qE - E. (x-dir) + qEy (y-dir). Given this, calculate the force on a 2.00 C charge placed at the origin. Do this in both polar and Cartesian coordinates. Electric Force in rectangular (x and y) form = X-component y-component Electric Force in polar (r and...
