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.

2. Relevant equations

f=ma, f=qe, e=v/d

3. The attempt at a solution

I said F=ma=QE therefore QE=ma and since E=V/d=1000/0.005=2x10^{5}

a=3.513x10^{16}m/s^{2}!

Then using s=ut+1/2at^{2}, t=5.335x10^{-10}s.

Thanks again for any help

Mike
