Choose the correct statement: Group of answer choices A proton tends to go from a region of low potential to a region of high potential. The potential of a negatively charged conductor must be negative. None of the other responses is correct. If V

TRUE. The potential of a negatively charged conductor must be negative

Explanation:

Let's examine each statement

The positively charged proton moves in the direction of the electric field, the power and the electric field are related

                ΔU = - E ds

                - U₀ = - E ds

                E = (U₀ –U_{f}) / s

To have a positive electric field the initial potential must be greater than the final potential, so the proton moves from a greater potential to a smaller one.

This statement is FALSE

The second statement

The potential has the same sign as the elective charge.

This statement is TRUE

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask
