Each picture (A-C) shows several charge distributions. Within each picture, there are several black dots. Draw the net electric field vector Enet at each of the marked dots. The lengths of your vectors should indicate the magnitude of the electric field at each point (places with larger magnitudes should have longer vectors). Feel free to draw additional vectors (in a different color) to help you construct Emet: A) B) +) + +

Please show all the steps, and solution separate at the end. Part (a)  Do this for the range r > R. Part (b)  Do this for the range r < R.

A negatively-charged object creates an electric field which can be measured at various locations in the region about it. An electric field vector is drawn for point X. Use your understanding of the electric field - distance relationship to draw E vectors for points A - E. (The length of the arrow should be indicative of the relative strength of the E vector.)

B) A uniform electric field is shown below. Using the information given, answer the questions shown. * A [1 * C D :Smallest A=(-1m,2m) C=(1m,2m) Rank, from largest to smallest the electric field at each of the points shown above. If two or more choices are equal, indicate this by putting an equal sign "=" between the letters in the ranking. B=(-1m,-1m) D=(1m,-1m) Largest: Rank, from largest to smallest the magnitude of the force on an electron placed at each of the points shown above. If two or more choices are equal, indicate this by putting an equal sign "=" between the letter in the ranking. Largest: :Smallest :Smallest O Rank, from largest to smallest the electric potential at each of the points shown above. If two or more choices are equal, indicate this by putting an equal sign "-" between the letters in the ranking. Largest: ) Rank, from largest to smallest the potential energy an electron would have if it were placed at each of the points shown. If two or more choices are…

Four equal charges (all +q) are placed on the corners of asquare with side length a. Please explain detailed steps and how you got to the answer.    a.)  Find an algebraic expression for the magnitude of theelectric force felt by the charge in the lower left-hand corner(circled) due to the other charges. b.) Make a sketch of the electric field lines associated with this charge distribution. Be sure to draw linesboth inside and outside the square.

Directions: Solve the problem below. Show your complete solutions. Round off your answers into 3 significant figures. 1. A particle has a charge of -5.8 nC. (a) What is the magnitude and direction of the electric field due to this particle at 0.30 m directly above it? (b) Where should the particle be when the electric field has a magnitude of 18.0 N/C?

Problem 1 Shown on the right is an electroscope. The sphere on the top, the leaves at the bot- tom, and the rod connecting them are made by conducting material. The spherical shell that blocks the influence of external electric fields is also made by conducting material but the contact with the rod is insulated, so that charges will not shuffle between the rod and the spherical shell. The electroscope is first negatively charged by touching the sphere with a negatively charged plastic plate. The leaves spread apart and we remove the plastic plate. We then bring a positively charged glass bar close to the sphere without touching the sphere. What happens to the leaves? Leaves (A) One leaf moves higher, the other lower. (B) Nothing changes to the leaves (C) The leaves spread farther apart. (D) The leaves get closer together. Clearly specify/circle your answer, and give a brief explanation.
