see alisha,
u must have studied tht the electric field inside a hollow conductor is zero or v can say tht electric lines of forces do not pass through a hollow conductor. now this property is used in a phenomena known as electrostatic shielding. the object to be shielded is enclosed inside a hollow conductor. now no external electric field can pass through the hollow conductor and hence the object is shielded from external electric field. this is known as electrostatic shielding.and as far as i kknow there are no seperate methods for shielding of earthed and non-earthed conductors. its same for both.
the best example for this is when u r told tht if lightning occurs and u r sitting inside a closed car(in this case the hollow conductor) u will not be harmed and thus u r electrostatically shielde.
HOPE THIS HAS SOLVED UR PROBLEM.
VOTE IF SATISFIED.
