EE 1; Homework 5: DUE MAY 21 st Wednesday 5 PM (THERE WILL BE A COLLECTION BOX IN FRONT OF TA’s OFFICE ENGR. IV RM# 64-118 ) (1) (a) Find the electric field ( E ) on the z-axis for z = h > 0 ? (b) Find the electric field ( E ) on the z-axis for z = -k where k>d ? (2) Find the capacitance of an isolated conducting sphere of radius b that is uniformly coated with a dielectric layer of thickness d . The dielectric has an electric susceptibility of χ e (3) Einstein’s theory of relativity stipulates that the work required to assemble a charge is stored as energy in the mass and is equal to mc

(4) A grounded metallic sphere of radius R is located at a distance of “d 1 ” from a point charge of “+Q1”, and at a distance of “d 2 ” from a point charge of “-Q2 as shown below. For this system calculate the potential for R ≤ R AND R > R . z Ring of radius “a” at z=0 plane with a line charge density of ρ Perfect conductor at z=-d plane d z=0 z=-d GND . +Q1 d 1-Q2 . d 2...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
