    What is the current due to the circulation of the u quark?

    Simply T = 2 pi r/v I = dq/dt = delta q/delta t here is there any chnage in q for a quark? nope! so, i = q(quark) v/2 pi r (since we are interested in the period - that is the time change) Let pi = (PI) and q = q of quark I = QV/(2(PI)r) the rest is very easy having in mind the...
