A proton accelerates from rest in a unifor electric field of 640 N/C. At some later time, its speed is 1.20X10^6m/s. Find the magnitude of the acceleration of the proton.

Hmm.. not sure what formula to use on this one.. can someone help?

You can use the formulae:

F_{net} = ma

E = \frac{F}{q}
 
hmm I am lookin for a right? so what am i suppose to plug in for m and q?
im confused..

im confused..
m = the mass of a proton
q = the charge of a proton
 
yeah i got that but its not given in the problem..
 
Don't you have a data sheet in your book. If not, I can give the values to you.
 
hmm.. is it m=1.67x10^-27? what is q?

Yes, and q is 1.60 \times 10^{-19}C
 
ok thanks a lot! i reallly appreciate it :-D
