‘Inside a conductor electrostatic field is zero’. Explain.
In the static situation, when there is no current inside or on the surface of the conductor, the electric field is zero everywhere inside the conductor.
A conductor has free electrons, the free charge carriers would experience force and drift.
In the static situation, the free charges have so distributed themselves that the electric field is zero everywhere inside.
The magnitude of electric field on the surface of a uniformly charged metalic spherical shell is $E$. If a hole is made in it using a insulating device, then the magnitude of electric field in the hole will be
The dielectric strength of air at $NTP$ is $3 \times {10^6}\,V/m$ then the maximum charge that can be given to a spherical conductor of radius $3\, m$ is
Given below are two statements.
Statement $I$ : Electric potential is constant within and at the surface of each conductor.
Statement $II$ : Electric field just outside a charged conductor is perpendicular to the surface of the conductor at every point.
In the light of the above statements, choose the most appropriate answer from the options give below.
Inside a hollow charged spherical conductor, the potential
