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.
How much work is moving the first electron?
How much work is moving the second electron?
What is the electrostatic energy of the alpha particle and two electrons at their final positions?
