My idea was to consider first the structure of the matrix element and to see if there are any possible constraints that we could use for parametrization. If I am not mistaken, we are dealing with the hadronic decay governed by QCD which conserves parity. Since we have a derivative operator...

Homework Statement Consider an infinitely long solid metallic cylinder having axis along kˆ.Consider a plane passing through axis of cylinder cutting it in two equal parts. In one part is a uniformly distributed current I1kˆ and in another part is a uniformly distributed current −I2kˆ. As...

This reminds me of a problem I saw in Irodov's book. There, we had no drag force, but still, it was very interesting to work on that problem. Thank you very much for your help. I feel that I've learned something new and important, something I will definitely use in the future :D

So I will write 492.4 m/s as a final answer. Thank you very much once again.

Yes, again a typo here. It should be kl=mv(t) = 0.98mv0 If we refer to the first equation, mv02/R = Bqv0, we see that v=BqR/m = BR\alpha , where \alpha = q/m v = 2\piR/T 2\piR/T = BR\alpha T = 2\pi/B\alpha Then the total time will be 2T t = 2T = 4\pi/B\alpha In my...

Thank you for your answer! In this part, I made a stupid error, writing v=B\alpham instead of v=B\alphaR. Since, we've already derived the relation between velocity and radius, I would say that velocity has to decrease by 2% in order for the radius to decrease by 2% as well. So using our...

Thank you very much! :D In the first part, I ment Bvq = mv2/R, which after simplyfing gives v = Bqr/m=B\alpham. In the second part, the quation becomes, -kv = m dv/dt, since drag force acts in the opposite direction (and since the the particle is spiraling, is it right to say that the...

Homework Statement A particle has specific charge α=q/m=108 C/kg. Then it enters a bubble chamber with magnetic field of induction B=10-2 T (the field is perpendicular to particle's velocity). Particle experiences drag force at the same time F = -kv, and as a consequence the particle spirals...
