Electric field from a cylinder
WebThe electric field is defined at each point in space as the force per unit charge that would be experienced by a vanishingly small positive test charge if held stationary at that point.: 469–70 As the electric field is defined in terms of force, and force is a vector (i.e. having both magnitude and direction), it follows that an electric field is a vector field. WebThus, the angle between the electric field and area vector is zero and cos θ = 1. The top and bottom surfaces of the cylinder lie parallel to the electric field. Thus, the angle between the area vector and the electric field is 90 degrees, and cos θ = 0. Thus, the electric flux is only due to the curved surface. According to Gauss law,

WebThe electric field about the inner cylinder is directed towards the negatively charged cylinder. Since this cylinder does not surround a region of space where there is another charge, it can be concluded that the excess charge resides solely upon the outer surface of this inner cylinder. The electric field inside the inner cylinder would be zero.
