How Fast Will a Charged Object Travel Between Differently Charged Plates?

[matt4u]

Homework Statement

A positively charged plate is help 5.0 cm above a negatively charged plate. The potential difference between the two plates is 500 MV. A negatively charged object of mass 3.00 grams is plaved on the bottom plate. If the object has a total charge of 100 million electrons, what is the speed at the top? (you can ignore gravity)

question 2. The electric potential in a region of space is given by V = by/(a^2+y^2). Calculate E

thanks a lot in advance
