An alpha particle (α), 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 α = 3.20×10⁻¹⁹ c and mα = 6.68×10⁻²⁷ kg , respectively.

Speed of the alpha particle is      

Explanation:

We have given charge on alpha particle

Mass of the alpha particle

Potential difference

We have to find the speed of the alpha particle

From energy conservation we know that

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
