Final answer:
In a high school physics context, 'Can you hold positive EDGE phrase?' may relate to concepts of electric potential. Equipotential surfaces do not intersect and a positively charged conductor can be at a negative potential if its surroundings have a higher positive potential.
Step-by-step explanation:
The phrase 'Can you hold positive EDGE phrase?' within the context of physics seems to relate to the concept of electric potential, which is typically discussed in a high school physics course. The questions regarding equipotential surfaces and positively charged conductors suggest the student is asking about principles of electrostatics within fields of charge.
Equipotential Surfaces
Equipotential surfaces are imaginary surfaces around a charge distribution where every point on the surface has the same electrical potential. In electrostatics, equipotential surfaces cannot intersect each other. This is because if they did, it would imply there are two different potential values at the point of intersection, which is not possible since a point in space can only have one value of electric potential.
Positively Charged Conductor and Potential
A positively charged conductor can indeed be at a negative potential. The potential of a conductor is determined relative to a reference point, typically taken at infinity where potential is assumed to be zero. If the surroundings of the positively charged conductor have an even higher positive potential, then the conductor can be said to have a negative potential compared to its surroundings.
