What is the amount of energy gained by a proton accelerated through a potential difference of 50 V?

The charge of proton 'e' is 1.602 x 10--19 C.
If it is subjected to a potential difference of 50 V, then the electrostatic potential energy gained by that proton will be 50 eV.
To get the energy in joule, replace 'e' by 1.602 x 10 --19.
Then, the required value is 8.01x10 --19 J
eV is the unit of energy which will be more convenient while dealing with very very small amount of energy. 1 eV = 1.602 x 10 --19 J

What is single electrode potential?
An electrode potential is the potential difference that develops when an electrode of one element is placed in a solution containing its ions. In a galvanic cell, electricity is produced by the electrode potential of the two metal electrodes and their corresponding electrolytes.
What is the difference between water and hydroxide?
The difference is the amount of hydrogen and oxygen
Which moleclues holds the greatest amount of potential energy?
one molecule of glucose
How can 9.0V batteries could have different potential energy?
Short answer: Voltage is not a complete measure of potential energy any more than the height of a weight is a complete measure of potential energy. In order to calculate energy you must multiply the voltage by the amount of current (Amps) that can be supplied to get power. Then you multiply that power by the amount of time it can be supplied to get energy (power is energy per unit time). to get the potential energy of a weight suspended above the ground you must multiply the height of the weight by it's mass and multiply that by the gravitation acceleration (about 9.8 meters per second squared on earth). Long answer: A 9V dry cell in a radio may only supply 111 milliamps for an hour or so while a 9V golf cart battery can supply 111 amps for an hour. Therefore the radio battery has a potential energy of 3.6 Kilojoules while the golf cart battery has 1000 times that amount, 3.6 Megajoules. Since a joule is equivalent to one kilogram accelerated over one meter at 1 meter per second squared and gravitational acceleration is 9.8 meters per second squared 3.6 Megajoules is about the same potential energy as a 1000 Kg (2200 pound) car at the top of a 367 meter (1200 feet) hill. The 9V battery has the potential energy of the same car .367 meters (1 foot 2.4 inches) up the hill. Quite a difference in potential energy.
What is the difference between .05mg and .075mg?
.075 is a larger amount
How can you get the largest voltage difference?
There is no such thing as a 'voltage difference'! 'Voltage' means 'potential difference', so what you appear to be asking is "How do you get the largest potential difference difference?'! Potential difference is caused by the separation of charges between two points. The greater the amount of charge separation, the greater the potential difference.
Explain how potential difference in a battery is similar to a staircase?
The potential difference in a battery is like the height of the stairs. The amount of charge separated in a battery is like the mass moved up the stairs. The potential energy in the battery is due to both the potential difference (volts) and the amount of charge that has been separated (coulombs).
How can works capacitors?
When connected to a d.c. supply, electrons are transferred from one plate and deposited on the opposite plate. This creates a potential difference across the two plates. This action continues until the capacitor's potential difference is equal (but opposite) to the potential difference of the d.c. source. If the source is then removed, the electrons cannot return to the original plate, other than through the dielectric, so the capacitor will hold that potential difference. By definition, the charge 'stored' on the capacitor is the amount of negative charge on the negative plate (not the sum of the charges on the two plates). Leakage current through the dielectric gradually reduces the potential difference across the plates.
Relation between potential difference work done and charge moved?
potential difference is the amount of work done in moving a unit charge from one point to another point. potential difference be V ,work done be J and charge be C.V=J\C
One way to make current is to use a what?
You can apply a potential difference across a wire to cause a current to flow through. Ohm's Law allows you to calculate the amount of current based on the voltage supplied and the resistance of the circuit. I = current V = voltage or potential difference R = resistance I = V/R
Is voltage measured in volts?
Voltage, along with electric pressure, electric tension, and electrical potential difference is measured in units of electric potential. This can be joules per coulomb or volts.AnswerFirst of all, there is no such thing as a 'voltage difference'. Voltage is already a 'difference', as it is an alternative name for 'potential difference'! 'Voltage difference', therefore, would mean 'potential difference difference', which makes no sense!The unit for potential and potential difference (voltage) is the volt, which is equivalent to a coulomb per second.
Define voltage in terms of electric potential energy and charge?
When unlike charges are moved farther apart, they gain electrical potential energy. Electrical potential difference is the change in potential energy per coulomb of charge. Voltage is the common name for electrical potential difference and is measured in volts (V). Electrical energy depends on the amount of charge and voltage. Electrochemical cells, or batteries, are a common source of voltage. We use voltmeters to measure potential difference. :)
What is electric potential in between twooppositely charged plates?
The electric potential difference is measured in volts. The amount of volts will depend on what kind of plates and the solution which the plates have been put in to.
What is an electron vault?
1 electron-volt is a small unit of energy. It's the amount of energy gained or lost by the (amount of electric charge on one electron) moving through a (potential difference of one volt). 1 joule of energy is the same as about 6,241,400,000,000,000,000 electron-volts.
If 110 V ac is applied to the primary what is the output potential difference?
This answer should contain the amount of turns that the primary and secoundary have.
What determines the amount of current a voltaic cell can produce?
Thew rate of corrosion determine the amount of current of a voltaic cell OR the potential difference of the two materials. --- R.B.DHRUV
Why Potential energy of an object at the earth's surface is not zero?
It may, or may not, be zero, depending on what you use as the reference level. The absolute amount of potential energy is physically meaningless; what matters is a difference in potential energy between two points.
