An electron with speed v0 = 27.5 X 106 m/s is traveling parallel to a uniform electric field of magnitude E = 11.4 X 103 N/C. How far will the electron travel before its velocity is zero?

Electron will travel to a distance of 0.189 m before its velocity is 0    

Explanation:

We have initial speed of the electron

Electric field

Charge on electron will be

Mass of electron

We know that Columbus force is equal to F = qE and according to newtons law force is equal to F = ma , here m is mass and a is acceleration

These two forces will be equal

So ma = qE

According to third equation of motion

So

s = 0.189 m

So electron will travel to a distance of 0.189 m before its velocity is 0
