(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

an electron is accelerated through a potential difference from 0v to N kv. It is then ejected through a slit and deflected 10* over a distance r of 2 cm.

find B ,v_f, and t(time)

2. Relevant equations

qdelta V = 1/2Me v_f^2 (solved for vf)

M(v/r)= qBsin[tex]\theta[/tex] solved for B

3. The attempt at a solution

As listed above I solved for the variables listed (assuming I did it right, please correct me if Im wrong)

but what is the relation of t to this, is it a kinematic or a break down of db/dt?
