When A proton initially at rest falls through a p.d of 25000v .what speed does it gain?
The kinetic energy gained by the proton is equal to the work done on it by the electric field. Using the equation for work, you can find the final velocity of the proton. Given the potential difference (voltage) of 25000 V, you can calculate the speed gained by the proton.
What is the difference in the charge of a proton and an electron?
The charge of a proton is positive, while the charge of an electron is negative.
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.
What happens to potential energy when a proton is brought closer to an electron?
The potential energy decreases as the proton is brought closer to the electron. This happens because the electric force between opposite charges causes them to attract each other, leading to a reduction in their potential energy as they get closer together.
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.
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

Is an alpha particle and a proton released from the centre of the cycltron and made to accelerated at the same cyclotron frequency?
the alpha particle will accelerate slower and follow a tighter/smaller spiral outward than the proton.
What facilitates the movement of K plus into epidermal cells of the root?
passage through selective channels, aided by the membrane potential created by proton pumps.
What is the difference in the charge of a proton and an electron?
The charge of a proton is positive, while the charge of an electron is negative.
What is difference between proton and positive charge?
There is no difference, they are one the same. A proton has a positive charge and a positive charge is a proton. Of course with the positive charge, it's simply having more protons than electrons.

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.
What is the difference of Charge of a proton and charge of a neutron?
a proton is positively charged whereas a neutron has no charge, it is neutral.
What is the difference in charge between a proton and a neutron?
The proton has a +1 charge, while a neutron has no charge, and is neutral.
What is the difference in the amount of charges in a proton and electron?
A proton and an electron have exactly opposite charges. If you take the charge of a proton as +1, then an electron has a charge of -1.
Where do electrons that flow through the two photosystems have their highest potential energy?
The electrons that flow through the two photosystems in the light-dependent reactions of photosynthesis have their highest potential energy at the beginning, when they are excited by sunlight and enter the electron transport chain. This potential energy is used to create a proton gradient across the thylakoid membrane, which is then harnessed to produce ATP through ATP synthase.
What happens to potential energy when a proton is brought closer to an electron?
The potential energy decreases as the proton is brought closer to the electron. This happens because the electric force between opposite charges causes them to attract each other, leading to a reduction in their potential energy as they get closer together.
