Law of gauss 1.Consider a disc of radius R with surface charge density σ(r, θ) =[ 2cos(θ)/r^ 2]+ [1C/πR^2].a) What is the electric field flow through a closed surface S that completely encloses the disc? b) Now a point load of -1C is placed near the surface S, but outside it. What will be the total electric field flow through...
Question on the Potential Energy of Macroscopic Springs
Design a “bungee jump” apparatus for adults. A bungee jumper falls from a high platform with two elastic cords tied to the ankles. The jumper falls freely for a while,with the cords slack. Then the jumper falls an additional distance with the cords increasingly tense. Assume that you have cords that are 13 m long, and that the cordsstretch in...

An electron with kinetic energy 228 eV is moving in a horizontal direction. The electron moves into a region where there is a uniform vertical electric field which has magnitude 3990 N/C. Find the smallest magnitude of a magnetic field that will cause the electron to continue to move horizontally. (1eV=1.6^10^(-19)J;mass of the electron=9.11*10^(-31)kg)
