What is the amount of work required to move a unit charge on Gaussian surface?

Suppose you are 1 cm away from an infinite flat sheet of charge +Q. At that point you measure an electric field E. If you measure the electric field at a point 3 cm away, it will be O a. E o b. E O c. a d.

(10% ) Problem 7: An infinite conducting cylindrical shell of outer radius ri-0.10 m and inner radius r2 0.08 m initially carries a surface charge density 0.15 μC/m2 A thin wire with linear charge density 1.3 μC m s nserted along the shells' axis. The shell and the wire do not touch and these is no charge exchanged between them Banchi, Stephen - banchis3@students.rowan.edu @ theexpertta.com - tracking id: 2N74-2F-82-4A-BAAB-13083.

The electric flux density of a charge distribution with spherical symmetry is given by (a³po -âr, r2 a 3r2 rpo D = r a C-

Problem 6: With -5.0 D corrective lenses, Juliana's distant vision is quite sharp. She has a pair of -3.5 D computer glasses that puts her computer screen right at her far point. How far away is her computer?

parallel-plate capacitors are widely used in electronics such as preventing direct current leakage. An electric field is generated between a pair of plates that has a surface charge density of 7.70 x 10^-6 C/m^2 The plates are seperated by 0.49 um. a) what is the magnitude of the electric field between the plates ? b) suppose the thickness of the plates doubled, would my answer increase, decrease, or remain the same?
