Solve a numerical of charge distribution

Asked by  | 27th Jan, 2010, 06:14: AM

Expert Answer:

Let the charges be Q1 and Q2 distributed over the two parts, but uniformly distributed.

F = kQ1(Q-Q1)/R2

As we can see the force is the function of Q1 only since Q, total charge and R, separation distance is consant.

dF/dQ1 = 0

k[-Q1 + (Q - Q1)]/R2 = 0

Q1 = Q/2

Hence Q2 = Q/2
