Important Questions from Applications of Gauss’s Law
According to Gauss’s law, the electric field due to an infinitely long thin charged wire varies as:
An infinitly long wire is charged uniformly with charge density λ and placed in air, the electric field at distance r from wire will be:
The variation of electric field with respect to distance from centre of a charged conducting spherical shell of radius R is given by :
Find the electric field outside the cylinder, a distance r from the axis using Gauss's law, if a long & straight wire is surrounded by a hollow metal cylinder whose axis coincides with that of the wire. The wire has a charge per unit length of λ, and the cylinder has a net charge per unit length of 2λ?
An isotropic radiation has a field pattern given by $E=\frac{10I}{r} v/m$ where I is the terminal current and r is the distance in meters. The radiation resistance of the antenna is ____________.
