If they made an oblique angle with the surface, what physical problem would arise?Why can electric field lines be denser near the pointed part of a conductor?A metallic sphere is given positive charge. In electrostatic condition, which statement about field inside and field lines outside is correct?Why must the tangential component of electric field at the surface of a conductor be zero?Inside an isolated conductor in electrostatic equilibrium, the field is zero. What is the most appropriate reason?Even when electric field inside an electrostatic conductor is zero, why can field exist just outside its surface?Why must the tangential component of the electric field at the surface of a conductor in electrostatic equilibrium be zero?
