Homework Statement
Two particles, of charges q1 and q2 are separated by distance d. The net electric field due to the particles is zero @ x=d/4.
With V=0 @ infinity, locate (in terms of d) any point on the x axis (other than infinity) at which the electric potential due to the two...
I think I solved it. You don't integrate. M is known to be the limiting population, and you just need to prove B_o*P_o/D_o which if you substitute is (a/b)
Take P(a-bP) --> (b/b)(P(a-bP), which will can be simplified to bP(a/b-P)
If you compare to kP(M-P), they are equal. a/b is M, which...
I am having the same problem (I have the same book, hoping bumping this will answer it). The error you had was you should START with dP/dt=aP-bP^2.
I started by separating the eqn into:
(1/aP-bP^2)dp=dt --> (1/(P(a-bP)))dP=dt
From there I tried partial fractions, but the answer seems way...
