Question

Suppose a large number of particles are bouncing back and forth between r-0 and x = 1, except that at each endpoint some escape. Let r be the fraction reflected each time; ther) is the fraction escaping. Suppose the particles start at 0 heading toward x = 1; eventually all particles will escape. Write an infinite series for the fraction which escape at x = 1 and similarly for the fraction which escape at x = 0, Sum both the series. What is the largest fraction of the particles which can escape at 0? (Remember that r must be between 0 and 1.) 16.

Explanation / Answer

a)not allowed. charge of etaon in 0 where as chare of proton is 1.so left hand side charge is 0 and in r.h.s. it is 2.so charge conservation violates.if one of them were anti proton then it does not violate charge conservation.

similar process has applied to verify charge conservation

b)not alllowed .>l.h.s. charge 0:r.h.s.charge +1

c)allowed >charge of l.h.s.(0)=charge of r.h.s.(0+0+0)

d)not allowed> charge of l.h.s(0) not equals to charge of r.h.s(3)

e)allowed >charge of l.h.s(0)=charge of r.h.s(1-1)
