As per the question, we can say that the net charge enclosed in the surface can be calculated using the formula of electric flux. It has been mentioned that the gaussian surface is spherical and is enclosed by 30 electrons. An enclosed gaussian surface is placed in the 3D space where its electrical flux is going to be measured. Gauss law is considered valid for any closed surface and for any distribution of charges. Ques. Can Gauss’ law be applied to all surfaces?Īns. In case Gauss theorem is applied to a point charge enclosed by a sphere, Coulomb’s law can be easily obtained. Note: Gauss law is considered a form of restatement of Coulomb's law. Hence, the changing magnetic fields cannot function as sources or sinks of electric fields.It is only the electric charges that can serve as sources or sinks of the electric fields.The charges outside the surface do not contribute to the electric flux.In any closed surface, the electric flux is only due to the sources (positive charges) and sinks (negative charges) of the given electric fields that are enclosed by it.Gauss theorem statement claims an important corollary as well: Thus, the number of electric field lines that enter the surface is equivalent to the field lines exiting the surface.Assuming that the charges are enclosed by a surface, the net electric flux will be zero.Gauss theorem corresponds to the ‘flow’ of electric field lines (flux), within a closed surface, to the charges.Thus, if ϕ is total flux and ϵ 0 is electric constant, then the total electric charge Q which is enclosed by the surface can be represented as, Q = ϕ ϵ 0Īs per Gauss theorem, the net flux passing via a closed surface is in direct proportion to the net charge in the volume enclosed by it. Gauss law has an inverse square relation based on the distance comprised in Coulomb's law.Īlso Check: Verify the laws of parallel combination of resistances using a metre bridge experimentĪccording to the Gauss theorem, the total charge enclosed in a closed surface is in proportion to the total flux of the surface. The choice of a suitable Gaussian surface can facilitate it. Gauss law is easier to calculate the electrostatic field when the system has some symmetry. However, it can be said that the Gaussian surface can pass through a continuous charge distribution.This is likely because the electric field present due to a system of discrete charges is not well defined at the location of any charge (moving near the charge, the field grows without any bounds).Gauss’s law can be applied to any surface, given that the Gaussian surface does not pass through any discrete charge.The surface to which Gauss’s law is applied is called the Gaussian surface.(The term Q, which is denoted on the right side of Gauss’s law, however, represents only the total charge inside the enclosed surface and not outside.) In the case when there are some charges inside and some outside the enclosed surface, the electric field is calculated due to all the charges, both inside and outside. The video below explains this: Gauss's Law in Magnetism Detailed Video Explanation: It includes the sum of all charges enclosed by the surface and these charges may be situated anywhere inside the surface.Gauss’s law is true for any closed surface, regardless of its shape or size. The net flux of the electric field through the given electric surface, divided by the enclosed charge should be a constant.The total flux of an electric field enclosed in a closed surface is directly proportional to the electric charge enclosed in the particular surface.Gauss law associates electric fields at the points on a closed surface and the net charge enclosed by that surface.Gauss’ law can be derived from Coulomb's law and vice versa. Gauss Law is studied in relation to the electric charge along a surface and the electric flux. It connects the electric fields at the points on a closed surface and its enclosed net charge. It was first formulated by Carl Friedrich Gauss in 1835. Gauss Law for magnetism is considered one of the four equations of Maxwell’s laws of electromagnetism. Gauss law, in a closed surface, indicates that the net flux of an electric field is directly proportional to the enclosed electric charge.
