# Sketch the pattern of electric field lines due to a conducting sphere having negative charge.

Electric field inside the conductor will be zero.
Becuase in electrostatics the charge resides at the surface of conductor and the free elecrons in the conductor will balance the charge on surface.
thus no electric field inside.

# Why does the charge inside the closed surface of a gaussian surface contribute to electric flux. Why doesnt it pass through as in the case of electric flux due to a charge that is situated outside? Ans: When we find electric flux through a surface, then we consider the charge enclosed by the surface. This is done because Gauss' law is defined in terms of charge enclosed. So, a charge that is situated inside the surface contributes to the flux.   Thank you for a quick response. However, the answer provided by you doesnt clarify my doubt. There was a clear reasoning provided in the video lesson, why charge outside does not contribute to the flux. The electric field lines produced by a charge situated outside pass through the gaussian surface. Therefore, the question iam asking is that, what happens in the case of charge situated inside.
