1. Given the electric field E=3xx^+5yy^V/m, find the work done in moving a point charge +2C a) from (3,0,0)m to (0,0,0)m and then from (0,0,0)m to (0,3,0)m. b) from (3,0,0)m to (0,3,0)m along the straight-line path joining the two points, as shown in the figure.
2. Find H in cartesian components at P(1,3,5) if there is a current filament on the z axis carrying 6 mA in the 2 direction.
3. The conductivity of a region with cylindrical symmetry is given by σ=2e−120ρkS/m. An electric field of 252 V/m is present. a) Find J : Use J=σE b) Find the total current crossing the surface ρ<ρ0,z=0, all ϕ
