If you carry out the integral of the electric field ∫E→.d→l for a closed path like that as shown in (Fig. 3.40), the integral will always be equal tom zero, independent of the shape of the path and independent of where charges may be located relative to the path. Explain why.

An infinity long uniform line charge distribution of charge per unit length λ lies parallel to the y-axis in the y−z plane at z = root 3 / 2 a (see figure). If the magnitude of the flux of the electric field through the rectangular surface ABCD lying in the x−y plane with its centre at the origin is λL/nε0 ( ε0 = permittivity of free space), then the value of n is
