An alpha particle which is the same as a helium-4 nucleus, is momentarily at rest in a region of space occupied by an electric field. the particle then begins to move. find the speed of the alpha particle after it has moved through a potential difference of ? 3.45×10? 3 v .the charge and the mass of an alpha particle are q? = 3.20×10? 19 c and m? = 6.68×10? 27 kg , respectively. if you had carried out the algebra using variables before plugging numbers into your expressions, you would have found that(vf)? =? 2q? ? ? v is measured in volts. to verify that this expression for (vf)? has the correct units of velocity, you need to perform some unit analysis. begin by finding the equivalent of a volt in terms of basic si units. what is a volt in terms of meters (m), seconds (s), kilograms (kg), and coulombs (c)?
