(adsbygoogle = window.adsbygoogle || []).push({}); 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?
