hi
i was approached by this problem,
prove q/m = (2V)/(B^2r^2) [2V over B-squared r-squared]
so far i have,
F[electric] = qE
F[magnetic] = Qvb
F[electric] = F[magnetic]
therefore, v = E/B
-----
now i am a bit confused/wrong
-----
E[kinetic] = (mv^2)/2
therefore, q x V = (mv^2)/2
therefore, q/m = E^2/(2VB^2)
jus by looking at the result, i have to get E= 2V/r.
any insights will be greatly appreciated...
if my method even correct?
