An insulating solid sphere of radius 3 m has 15 C of charge uniformly distributed throughout its volume. Calculate the charge contained in a Gaussian surface having a radius 1/2 that of the sphere. Present your answer accurately to 2 decimal numbers i.e 3.20. Do not include units!
Use GFSA (Given, Find, Solution, and Answer) on the given space below. Encircle your final answer, write it in scientific notation with 2 decimal places (if possible).
An cylinder with radius 1 m and length 1.5 m has an infinite line of charge with a linear charge density of 30 C/m. (Make an illustration of the problem) (a) What is the total charge enclosed by the Gaussian cylinder? (b) What is the electric flux through the cylinder due to the infinite line of charge? (c) Calculate the electric field at a point 3 m away from the infinite line of charge.
This is a challenging problem. Solve it on paper, writing out each step carefully. When doing calculations, do not round intermediate values. Note:
If you have approached the problem in a principled way, do not abandon your approach if your numerical answer is not accepted; check your
calculations!
Four protons (each with mass 1.7 x 10.27 kg and charge 1.6 x 10-19 C) are initially held at the corners of a square that is 5.1 x 10 mon
a side. They are then released from rest. What is the speed of each proton when the protons are very far apart? (You may assume that
the final speed of each proton is small compared to the speed of light.)

Four 10nC positive charges are located in the z = 0 plane at the corners of a square 8cm on a side. A fifth 10nC positive charge is located at a point 8cm distant from the other charges. Calculate the magnitude of the total force on this fifth charge for e = €0: Arrange the charges in the xy plane at locations (4,4), (4,-4), (-4.4), and (-4,-4). Then the fifth charge will be on the z axis at location z = 4/2, which puts it at 8cm distance from the other four.
