What is meant by Gaussian surface?
A Gaussian surface (sometimes abbreviated as G.S.) is a closed surface in three-dimensional space through which the flux of a vector field is calculated; usually the gravitational field, the electric field, or magnetic field.
What is the difference between equipotential and electric potential?
An equipotential line is a line along which the electric potential is constant. An equipotential surface is a three-dimensional version of equipotential lines. Equipotential lines are always perpendicular to electric field lines.
What do you mean by equipotential difference?
Any surface over which the potential is constant is called an equipotential surface.In other words, the potential difference between any two points on an equipotential surface is zero. Some important properties of equipotential surfaces : 1. Work done in moving a charge over an equipotential surface is zero.
What is Gauss’s law used for?
Gauss’s Law is a general law applying to any closed surface. It is an important tool since it permits the assessment of the amount of enclosed charge by mapping the field on a surface outside the charge distribution. For geometries of sufficient symmetry, it simplifies the calculation of the electric field.
What is Gaussian surface and its properties?
Answer: The Gaussian surface is an arbitrary closed surface in three-dimensional space through which flux of vector field ( the gravitational field or magnetic field) is calculated. The examples of some valid Gaussian surfaces include the surface of sphere, cylinder, cube etc.
What is called Gaussian surface Class 12?
What is Gaussian Surface? The Gaussian surface is known as a closed surface in three-dimensional space such that the flux of a vector field is calculated. These vector fields can either be the gravitational field or the electric field or the magnetic field.
What is the general relation between electric field and potential?
The relationship between potential and field (E) is a differential: electric field is the gradient of potential (V) in the x direction. This can be represented as: Ex=−dVdx E x = − dV dx . Thus, as the test charge is moved in the x direction, the rate of the its change in potential is the value of the electric field.
What is an equipotential surface give example?
a surface all of whose points have the same potential. For example, the surface of a conductor in electrostatics is an equipotential surface. In a force field the lines of force are normal, or perpendicular, to an equipotential surface.
What is an equipotential surface?
The equipotential surface is defined as a surface with same potential at all points on it. In other words, the potential difference between any two points on the equipotential surface should be zero. Was this answer helpful? Thank you. Your Feedback will Help us Serve you better.
What are the equipotential surfaces of a spherical conductor?
For a point charge, the equipotential surfaces are concentric spherical shells. For a uniform electric field, the equipotential surfaces are planes normal to the x-axis The direction of the equipotential surface is from high potential to low potential. Inside a hollow charged spherical conductor the potential is constant.
What are Gaussian surfaces and why are they important?
Gaussian surfaces have relevance Gauss’s law, and we can choose any Gaussian surface that’s of equipotential surfaces; the shape is determined by the charge.
Is motion along an equipotential perpendicular to E?
In other words, motion along an equipotential is perpendicular to E. One of the rules for static electric fields and conductors is that the electric field must be perpendicular to the surface of any conductor. This implies that a conductor is an equipotential surface in static situations.
