Physics Flux

The electric flux through the surface shown in Figure Ex27.10 is 15.0 Nm2/C, and the electric field makes an angle á = 70° with the surface. What is the electric field strength? The surface is a 10cm by 10cm square.

  1. E.dA is flux
    E*Area*cos20=flux

    check the angle. Angles are measured to the normal.

  3. Flux = E*A
    E = Flux/A
    E = Flux/(0.1^2*cos(20))
    = 1596.2667 N/c
