WebApr 26, 2015 · It is because, say, a positive charge is place near you. You are grounded. So since human body is a conductor, it carries negative charge from the ground to counteract that electric field. If you make contact with the charged object, the entire charge floes to the ground and the object becomes neutral. Share Cite Improve this answer Follow WebMay 19, 2024 · If the electric field is bringing opposite charges together the electric field is doing positive work on each causing each to lose potential energy and gain kinetic energy. The force the field applies to each charge is in the same direction as their displacement. The gravity analogy is the gravitational field doing work on a falling object.

WebThus, if we move a positive charge in the direction of the electric field then we do negative work (i.e., we gain energy).Likewise, if we move a positive charge in the opposite direction to the electric field then we do positive work (i.e., we lose energy).Consider a set of point charges, distributed in space, which are rigidly clamped in position so that they cannot … WebJul 26, 2015 · Electric field is not negative.
