0An infinitely long thin non-conducting wire is parallel to the \( Z \)-axis and carries a uniform line charge density \( \lambda \). It pierces a thin non-conducting spherical shell of radius \( R \) in such a way that the \( \operatorname{arc} P Q \) subtends an angle \( 120^{\circ} \) at the centre \( O \) of the spherical shell, as shown in the figure. The permittivity of free space \( \varepsilon_{0} \). Which of the following
\( \mathrm{P} \)
W a) The electric flux through the shell is \( \sqrt{3} R \lambda / \varepsilon_{0} \)
b) The \( z \)-component of the electric field is zero at all the points on the surface of the shell
(c) The electric flux through the shell is \( \sqrt{2} R \lambda / \varepsilon_{0} \)
d) The electric field is normal to the surface of the shell at all points
