(a)
To explain: Whether it is possible for a particle to be both lepton and a baryon.
(a)
Answer to Problem 17Q
No, it is not possible for a particle to be both lepton and a baryon.
Explanation of Solution
Introduction:
Elementary particles are the basic building blocks of all matter. Nowadays the basic constituents of matter are considered to be quarks.
Leptons include electrons, positrons and neutrinos. They don’t contain any quarks. On the other hand, the baryons consist of three quarks bounded by a strong force between them. Hence, it is not possible for a particle to be both lepton and a baryon.
Conclusion:
No, it is not possible for a particle to be both lepton and a baryon.
(b)
To explain: Whether it is possible for a particle to be both a baryon and a hadron.
(b)
Answer to Problem 17Q
Yes, it is possible for a particle to be both hadron and a baryon.
Explanation of Solution
Introduction:
Elementary particles are the basic building blocks of all matter. Nowadays the basic constituents of matter are considered to be quarks.
Both baryon and hadron consists of quarks. Hadron consists of two or more quarks while baryon consists of three quarks. So, hadron is basically a baryon. Hence, it is possible for a particle to be both hadron and a baryon.
Conclusion:
Yes, it is possible for a particle to be both hadron and a baryon.
(c)
To explain: Whether it is possible for a particle to be both a meson and a quark.
(c)
Answer to Problem 17Q
No, it is not possible for a particle to be both a quark and a meson.
Explanation of Solution
Introduction:
Elementary particles are the basic building blocks of all matter. Nowadays the basic constituents of matter are considered to be quarks.
A meson consists of a quark and a anti-quark. So, it is not possible for a particle to be both quark and a meson.
Conclusion:
No, it is not possible for a particle to be both a quark and a meson.
(d)
To explain: Whether it is possible for a particle to be both a lepton and a hadron.
(d)
Answer to Problem 17Q
No, it is not possible for a particle to be both a lepton and a hadron.
Explanation of Solution
Introduction:
Elementary particles are the basic building blocks of all matter. Nowadays the basic constituents of matter are considered to be quarks.
Lepton is an elementary particle that doesn’t consists of quarks. But hadron is made of three quarks or a pair of quark and anti-quark. So, it is not possible for a particle to be both a lepton and a hadron.
Conclusion:
No, it is not possible for a particle to be both a lepton and a hadron.
