A uniformly charged and infinitely long line having a liner charge density \[\lambda \] is placed at a normal distance \[y\] from a point O. Consider a sphere of radius \[R\] with O as the center and \[R\] > \[y\]. Electric flux through the surface of the sphere is

\[\frac{\lambda \sqrt{{{R}^{2}}+{{y}^{2}}}}{{{\varepsilon }_{0}}}\]

\[\frac{2\lambda R}{{{\varepsilon }_{0}}}\]

\[\frac{2\lambda \sqrt{{{R}^{2}}-{{y}^{2}}}}{{{\varepsilon }_{0}}}\]
