An electron starts from rest 27.0 cm from a fixed point charge with Q = -8.00 nC .

How fast will the electron be moving when it is very far away?

------------------

Many chemical reactions release energy. Suppose that at the beginning of a reaction, an electron and proton are separated by 0.135 nm , and their final separation is 0.101 nm .

How much electric potential energy was lost in this reaction (in units of eV)?

---------------------------------------

A 0.21-F capacitor is desired. What area must the plates have if they are to be separated by a 3.2-mm air gap?
