Question

Electric field near a charged plane conductor is ​

Answer 1

Explanation:

The electric field is zero inside a conductor. Just outside a conductor, the electric field lines are perpendicular to its surface, ending or beginning on charges on the surface. Any excess charge resides entirely on the surface or surfaces of a conductor.

Answer 2

Electric field close to a charged plane conductor is ​E =(σ/∈₀)n

Explanation:

• A conductor is a material wherein charges can move freely.
• Therefore any electric field forces the charges to arrange themselves till a static equilibrium is reached.
• This in turn means that Inside a conductor E=zero everywhere, ρ = zero and any free charges have to be at the surfaces.
• Inside a conductor  the surfaces of a conductor are an equipotential and the potential V is constant  .
• The electric field simply outside a conductor have to be normal to the surface and proportional to the surface charge density: E =(σ/∈₀)n

Answer = E =(σ/∈₀)n
