Doesn't seem like they can. If they could, then that would put
two different potentials along the intersection.
No, two equipotential surfaces cannot intersect. These are surfaces where the gradient of potential is zero always.
No. If two equipotential surfaces intersect, then there would be two values of electric potential at the point of intersection, which is not possible.
0, because its equipotential surface
If two circles intersect then they have to intersect at two points.
Equipotential lines are lines that are perpendicular to the lines representing the electric field of a particle. A particle can travel freely of equipotential lines without doing any work.
An equipotential surface has the same value of potential. Thus, work done would be zero. Work done = Charge X Potential difference
If two different lines intersect, they will always intersect at one point.
No. That would mean that a place had two different air pressures at once. Not possible.
No, two straight lines can intersect at only one point and that is their point of intersection.
When the two surfaces touch but do not intersect one another.
Two lines that are not coplaner exist on two different planes. These lines do not and will not intersect by simple definition. It is however, when speaking of three or more lines, when the possibility that two or more of them may intersect.
For conductors, the electric field perpendicular to its surface and no field exist within the conductor. As a result the equipotential lines are found near the surface. They are parallel to the surface since equipotential are perpendicular to field lines.
