How much work does the electric field do in moving a proton from a point with a potential of plus 140 V to a point where it is -80 V?

Work = (Charge)x(Voltage change). The Charge on a proton is +e. The change in voltage is (-80 V - 140 V) = -220V. So it is -220 eV. It is negative, because the proton has moved to a lower potential, and therefore gave up energy to the field.

the proton that does the work. The field just lays back and soaks it up, doing
'negative' work.
Quantitatively, that would be 60 proton-volts of energy. I may be terribly mistaken,
but right at this moment, I believe that's the same as 60 electron-volts.
That's about 1.041 x 10-17 joule.

If a proton moved from 0 V potential to 5 V potential would its potential energy increase or decrease?
Electric field points from high potential to low potential. Positive particles had tendency to follow electric field. If you are moving the particle against this tendency you are doing work, and this work give more potential energy to the particle.
Why is electric potential inside a ring conductor on a conducting paper that has elctric field zero?
As long as there is any electric potential, charges continue moving around, until everything is balanced.
Is an electric field a potential field?
no electric field is not a potential field .ELECTRIC FIELD IS A SCALAR QUANTITY WHERE AS POTENTIAL IS THE VECTOR QUANTITY. NO SCALAR QUANTITY HAS A FIELD SO THERE IS NO RELATION BETWEEN ELECTRIC FIELD AND POTENTIAL OR IN OTHER WORD POTENTIAL HAS NO FIELD <<>> An electric field is a vector field, because it has magnitude and direction. A pair of charged parallel plates has an electric field between them directed from the negative to the positive plate. The electric field is the gradient of the potential, which is another field but a scalar one. A field is just a quantity with a value that depends on positon. The potential is measured in volts and if one plate is grounded and the other at positive potential V, the potential rises from zero to V as the position changes from the lower plate to the top one.
Moving electric charges will interact with?
Moving electric charges will interact with an electric field. Moving electric charges will also interact with a magnetic field.
If potential is constant throughout a given region of space can you say that electric field is zero in that region?
If the electric field is zero, the electric potential is a constant value, but it does not tell you what that value is. All the electric field tells you is how the electric potential changes within the region you are looking at. If the electric potential at one end of a cylindrical region is 7 V and the electric field is zero within the whole cylinder, then the electric potential is 7 V at the other end, or somewhere in the middle, or on the side, and so forth. An electric field of zero tells you the potential does not change, but doesn't say anything about what it is outside of the region you're looking at.
If a proton moved from 0 V potential to 5 V potential would its potential energy increase or decrease?
Electric field points from high potential to low potential. Positive particles had tendency to follow electric field. If you are moving the particle against this tendency you are doing work, and this work give more potential energy to the particle.
A proton is in an electric field and has an electric potential energy of 0.5 J What is the electric potential voltage that it experiences?
First off you know that when it says "Proton" you should know that its a Positive (+) Charged subatomic particle! Now You use the equation that says --> Volt = Electric Potential Energy / Q Volt = 0.5 / +1 (proton) Volt = 0.5
Relationship between electric field intensity and electric potential?
Electric field intensity is related to electric potential by the equation E = -dV/dx, where E is the electric field intensity, V is the electric potential, and x is the distance in the direction of the field. Essentially, the electric field points in the direction of decreasing potential, and the magnitude of the field is related to the rate at which the potential changes.
What type of fields surround every proton?
A 'gravitational field' and an 'electric field' surrounds every proton.
Why is electric potential inside a ring conductor on a conducting paper that has elctric field zero?
As long as there is any electric potential, charges continue moving around, until everything is balanced.
What is the magnitude of the electric field due to a proton at a distance r NM?
The magnitude of the electric field is 2.5.

How much work does the electric field do in moving a proton from a point with a potential of plus 145 V to a point where it is 75 V?
First of all, in moving from a more positive place to a more negative place, it's the proton that does the work. The field just lays back and soaks it up, doing 'negative' work. Quantitatively, that would be 70 proton-volts of energy. I may be terribly mistaken, but right at this moment, I believe that's the same as 70 electron-volts. That's about 1.215 x 10-17 joule.
Can moving electrons through a magnetic field can produce an electric current?
Electrons moving is an electric current. An electric current moving at an angle to a magnetic field will produce a Force.
