An alpha particle alpha which is the same as a helium-4, Ask an Expert

Academics

An alpha particle (alpha), 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?3V.

The charge and the mass of an alpha particle are q_{\alpha} = 3.20×10?19C and alpha = 6.68×10?27kg , respectively.

What is the final velocity of the alpha particle, Vf of alpha?
