Assertion: E in outside vicinity of a conductor depends only on the local charge density `sigma`.
Reason:`vec(E)` in outside vicinity of a conductor is given by `(sigma)/(epsilon_(0))`

Assertion(A): vec(E) in the outside vicinity of a conductor depends only on the local charge density sigma and it si independent of the other charges present anywhere on the conductor. Assertion(R ): vec(E) in outside vicinity of a conductor is given by (sigma)/(epsilon_(0))

The electric intensity at a pont near a charged conductor having a charge density sigma is

Show that electric intensity at a point outside a charged cylinder is given by , E = (sigma R)/(in_0 kr)

The electric intensity at a point near a charged conductor of surface charge density sigma is

Show that electric intensity at a point outside a charged sphere is given by, E = (sigma R^2)/(in_0 kr^2)

The mechanical stress of a charged conductor of charge density sigma is always directed outwards because

The electric field E, current density j and conductivity sigma of a conductor are related as

If a conductor has a potential V ne 0 and there are no charges anywhere else outside then,
