wud the field lines emerging frm a finite uniform line of charge( like a thin rod) b perpendicular to it??if so then a detailed explanation of the logic bhind it is required.

also,to prove tht estatic forces can not keep a body in stable equilibrium,we say tht if we assume tht estatic forces can keep a charge in equilibrium, then this shud mean tht field lines shud enter a + charge nd leave a - charge. did not understand logic behind it....plz xplain the Concept Properly.

hellooo, wot kind of a site is this?? even the experts don't answer questions ...i hope i ll get my nickels back

....

NO ANSWER????????????any experts ou there??

THE electric field lines will be like this

don't forget to RATE!!!!

This is essential for conductor to be in equilibrium

Conductor at Equilibrium

For a conductor at equilibrium:

1. The net electric charge of a conductor resides entirely on its surface. (The mutual repulsion of like charges from Coulomb's Law demands that the charges be as far apart as possible, hence on the surface of the conductor.)

2. The electric field inside the conductor is zero. (Any net electric field in the conductor would cause charge to move since it is abundant and mobile. This violates the condition of equilibrium: net force = 0.)

3. The external electric field at the surface of the conductor is perpendicular to that surface. (If there were a field component parallel to the surface, it would cause mobile charge to move along the surface, in violation of the assumption of equilibrium.)
