Question:
Two electrons are fired at 3.5 x 10^6 m/s directly at each other.
(a) Calculate the smallest possible distance between the two electrons.
Attempt:
I tried Ee=Ek for this question and this is how it went.
Note*(q1=q2)
Ee=Ek
kq^2 = 0.5mv^2
r
r= kq^2
0.5mv^2
= (9.0x10^9(N x m^2)/C^2)(1.6x10^-19C)^2
0.5(9.1x10^-31kg)(3.5x10^6m/s)^2
= 4.1x10^-11m
I don't seem to be getting the right answer. Can someone please tell me what I'm doing wrong?
