BackThe electric flux through each surface of a cube is given below. Which surfaces of the cube does the electric field run parallel to?
Φ1 = 100 Nm2 /C Φ4 = 0 Nm2 /C
Φ2 = 20 Nm2 /C Φ5 = −40 Nm2 /C
Φ3 = 0 Nm2 /C Φ6 = −80 Nm2 /C
Where does the normal vector point for a spherical shell?
What is the total flux through the two surfaces depicted in the following figure? Note that surface 1 has an area of 50 cm2 and surface 2 has an area of 100 cm2 , and E = 500 N/C.
A uniform electric field points in the positive x direction and has a magnitude of 40N/C. What is the net flux through a cube with sides 4.0cm? The cube has one corner on the origin and the positive x, y, and z axes form three of its edges.
A hemispherical surface with radius in a region of uniform electric field has its axis aligned parallel to the direction of the field. Calculate the flux through the surface.
