A very long uniformly charged wire oriented along the axis of a circular ring of radius R rests on its centre with one of the ends (as shown in figure). The linear charge density on the wire is λ. Evaluate the flux of the vector E→ across the circle area.

A cylinder of radius R and height h is placed in uniform electric field as shown in Fig. (a) if the axis of the cylinder made inclined with vertical as shown in Fig. (b). Calculate the flux of electric field entering the cylinder.
