Homework Statement
Hello, I wonder if anyone could check my answer to this problem.
Thanks in advance
An electron is liberated from the lower of two parallel plates separated by a distance of 5mm. The upper plate has a p.d. of 1000v relative to the lower plate. How long does it it take for the electron to reach to upper plate.
Homework Equations
f=ma, f=qe, e=v/d
The Attempt at a Solution
I said F=ma=QE therefore QE=ma and since E=V/d=1000/0.005=2x105
a=3.513x1016m/s2!
Then using s=ut+1/2at2, t=5.335x10-10s.
Thanks again for any help
Mike
