Charge density on the surface of conductor | 12th Physics #shorts

If q is the charge per unit area on the surface of a conductor, then the electric field intensity at a point on the surface is

Across the surface of a charged conductor

The electric field intensity on the surface of a charged conductor is

An uncharged conductor of arbitrary (non-spherical)shape, has a spherical cavity with a point charge q kept at its centre. The induced surface charge densities at outer surface of conductor and inner surface of cavity in electrostatic condition are respectively

The surface density of charge on the surface of a charged conductor in the air is 26.5 muCm^(-2) . The the outward force per unit area of the charged conductor is (epsilon_0=8.85xx10^-12C^2N^-1m^-2)

The surface density of charge on the surface of a charged conductor in air is 0.885 muC//m^(2) . If epsi_(0) =8.85xx10^(-12) C^(2)//N-m^(2) , then the outward force per unit area of the charged conductor is

Let at any instant point charge is at x distance from centre Q. Net charge on surface of conductor at this instant
