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...
Electric Field Activity By the end of this activity you will be able to do the following: • Recognize correct and incorrect features in electric field lines • Qualitatively sketch field lines for a charge distribution. • Qualitatively sketch the motion of a charge given the field lines. 1. General Features of electric field lines Electric field lines are a way of repre- senting the electric field. There are three rules for drawing these lines: • At each point Ē...
(3) A point charge of 10 nC sits at the origin. [5 pts] (a) Sketch the point charge and it electric field lines. (b) Now sketch a spherical surface of radius 2 m that sits on the x-axis at x-4m. Assume there is no charge on the spherical surface. (Sketch in 2D i.e. include just the projection of the sphere on the x-y plane.) (c) How many of your drawn lines enter the spherical surface? (d) How many lines leave...
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....
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...
1.16 Consider an infinite non-conducting plane having a charge density of 1 C/m^2. Sketch electric field lines and indicate the value of electric field 1 m away from the plane 1.17 Let’s add a point charge of -1C, at a distance 1 m from the plane in problem 1.16. What would be the force onto the charge? 1.18 How much work will it take to remove the point charge in 1.17 from where it was infinitely far away from the...
