1) Which of the following statements about electric fields and equipotential surfaces are correct? (check all that apply) a)The electric field direction is always from higher potential to lower potential. b)The number of electric field lines per unit area perpendicular to the field lines is proportional to the strength of the electric field in that region c)Equipotential surfaces are surfaces where the potential is constant over this surface. d)Electric field lines begin on positive charges and end on negative charges....

Gauss's Law in 3, 2, and 1 Dimension
Gauss's Law in 3, 2, and 1 Dimension Gauss's law relates the electric flux \(\Phi_{E}\) through a closed surface to the total charge \(q_{\text {end }}\) enclosed by the surface:Part ADetermine the magnitude \(E(r)\) by applying Gauss's law.Express \(E(r)\) in terms of some or all of the variables/constants \(q, \tau\), and \(\epsilon_{0}\).Part BBy symmetry, the electric field must point radially outward from the wire at each point; that is, the field lines lie in planes perpendicular to the wire. In solving for the magnitude of...
