Describe schematically the equipotential surfaces corresponding to (a) a constant electric field in the z-direaction . (b) a field that uniformaly increases in magnitude but reamins in a constant (say,z) direction. (c) a single positive charge at the origin, and (d) a uniform grid consisting of long equally spaced parallel charged wires in a plane. |

Answer» Solution :By defination an equipotential SURFACE is that EVERY point of the which potential is the same. In the four cases given above, (a) Equipotential surfaces are planes PARALLEL to x - y plane. These are EQUIDISTANT. (b) Equipotential surfaces are places parallel to x - y plane. As the FIELD increases uniformly distance between the planes decreases. (c ) Equipotential surfaces concentric spheres with origin at the centre. (d) Equipotential surfaces have the shape which changes periodically at far off distance from the grid. |
