Question

An alpha particle is at rest in region of space occupied by anelectric field. The particle then begins to move. Findthe speed of the alpha particle after it has moved through apotential difference of -3.45 x 10-3 V Charge and mass of alpha particle are 3.20 x 10 -19C and mass = 6.68 x 10 -27 kg An alpha particle is at rest in region of space occupied by anelectric field.

Explanation / Answer

energy is conservative. W0=K+W1 K=W0-W1=V*q=3,45e-3*3,2e-19=1,104e-21(J) K=mv^2/2 so v=sqrt(2K/m) plug K in we have. v=575m/s
