A positively charged particle, which charge [tex]q[/tex] and mass [tex]m[/tex], reached an area with an electric field and a magnetic field. Electric field E is at y>0 and its direction is -y. Magnetic field B is at y<0 and its direction is at -z (into the paper). The particle enters at y=h at intial speed [tex]v_0[/tex]

Question: Determine the time it takes the particle to reach y=0.

Attempt: I'm not sure what equations are relevant in this question. I know there's

[tex]E = k \frac{q}{r^2}[/tex] and

[tex]F = qE[/tex]

but what formula has time in it?

(this portion of the question only deals with the electric field. The other parts involve the magnetic field. I'm sure once I understand this section, I'll understand the rest of the parts)

Thanks!
