question 3 please explain option B,D also
Hope this answer helps.
- The electric field from the non - conducting uniformly charged wire will be perpendicular to the wire. So, we can say that the direction of the electric field is completely along the x component of the electric field vector. Hence, the z - component of the electric field will be zero. Option B is correct.
- We can see that the electric field from the non - conducting wire will be always perpendicular to the wire but it will never be perpendicular to the surface non - conducting spherical shell at every point. However, it will be perpendicular to the surface of the spherical shell at some point so option D is wrong.
