The potential difference across two plates is 20.0 V. If the plates are 0.00500 m apart, what is the electric field between them? Unit= N/C

Aproton is projected toward a fixed nucleus of charge +ze with velocity vo. initially the two particles are very far apart. when the proton is a distance r from the nucleus its velocity has decreased to 1/2vo. how far from the nucleus will the proton be when its velocity has dropped to 1/4vo?
