A student starts working on a problem on Gauss' theorem to calculate the flux and hence the electric field at a given point due to a system of discrete charges. The teacher gives instructions and the student responds to each instruction as per her understanding of the concept. State whether the student's response is correct or incorrect. Give a reason for your answer.
Examiner: Draw a Gaussian surface for the given system of charges.
Student: Draws a symmetric surface passing through the point at which the electric field is to be calculated.
Answer
Answer
Official answer keyResponse is correct. The Gaussian surface is an imaginary closed surface around a charge.
