An ion with twice the charge of an electron is accelerated from rest to a kinetic energy of 32.0 keV by the electric field between two parallel conducting plates. If the plates are separated by a distance of 2.00 cm, what is the electric field strength between the plates?
Proton charge is C.
A negative hydrogen ion is a hydrogen atom containing two electrons. An electron and a negative hydrogen ion are accelerated through the same potential. Find the ratio of their speeds after acceleration, assuming the speeds are non-relativistic. Use a value of kg for the mass of the hydrogen ion.
If a beam of protons were to gain its kinetic energy in only one pass through a potential difference to move with the speed of 0.400, how high would this potential difference have to be?
An object with a charge µC is initially at rest at a distance of 2.0 m from a fixed charge µC. What is the kinetic energy of the object when it is at a distance of 1.0 m from ?
A beam of protons is produced by a Van de Graaff generator. The beam produces a 5.00 mA current and the protons in the beam have energies of 1.00 keV.

If the object starts accelerating from rest at a point 4.0 cm from the fixed charge, what speed will the object have when it is 8.0 cm away from the fixed charge?
To form a hydrogen atom, a proton is fixed at a point and an electron is brought from an effectively infinite distance from the proton to a distance of m from it. Find the magnitude of work done moving the electron.
To form a helium atom, an alpha particle that contains two protons and two neutrons is fixed at one location, and two electrons are brought in from far away, one at a time. The first electron is placed at m from the alpha particle and held there while the second electron is brought to m from the alpha particle on the other side from the first electron, as shown.
The charge of an electron is C and the charge of a proton is C.
