\nFor a conductor in electrostatic equilibrium, the electric field lines are always perpendicular to the surface, and for a positively charged object, they point outwards.
\n<\/section>\n
\nIn electrostatic equilibrium, the electric field inside a conductor is zero, and any net charge resides on the surface. If the electric field had a component parallel to the surface, charges would move along the surface, and the conductor would not be in equilibrium. Therefore, the electric field lines must be perpendicular (at right angles) to the surface of the conductor. For a positively charged object, electric field lines originate from the positive charges and point away from them. For a sphere, this direction is radially outwards from the centre.
\n<\/section>\n
\nFor a negatively charged conducting sphere, the electric field lines would also be at right angles to the surface but would point inwards towards the centre of the sphere, terminating on the negative charges on the surface.
