Are Conductors Truly Equipotential?

Click For Summary
Conductors are indeed equipotential, meaning that the electric potential is the same throughout the entire conductor. This is because the electric field inside a conductor is zero, which prevents free electrons from moving. On the surface, the electric field is perpendicular to the surface, maintaining this equipotential condition. Therefore, the statement that conductors are equipotential is true. Understanding these principles is essential for solving related physics problems.

Homework Statement


in my exam, i had the following question
say true or false--conductors are equipotential.
what is the answer?

What do you think? :wink:
Hint: When a conductor is equipotential, E-field inside the conductor is zero and E-field on the surface of the conductor is perpendicular to the surface. Can free electrons move under that circumstance?
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
