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

Consider a positive point charge +q, immersed in plasma. Show that the net charge in the Debye shielding cloud exactly cancels the test charge. Assume the ions are fixed and that e*phi <<< kTe.

2. Relevant equations

f(u) = A exp [-(1/2*m*u^2 + q*phi)/k_b*T_e]

u is the x component of velocity

3. The attempt at a solution

Really lost on this one. I think I could make a hand waivey argument with Gauss's Law but I don't see where to go on this one.
