QUESTION: 1

Order of ionization power of α,β, and γ rays is

Solution:

Since α rays has more charge than β and γ has no charge therefore order of ionization is α > β > γ.

The correct answer is: α > β > γ

QUESTION: 2

The binding energies of the nuclei P^{n} and Q^{2n} are *x* and *y * joules. If 2x > y then the energy released in the reaction P^{n} + P^{n} → Q^{2n}, will be

Solution:

The correct answer is: -(2x - y)

QUESTION: 3

A radioactive element Th(_{84}Po^{216}) can undergo α and β are type of disintegration with half lives, T_{1} and T_{2} respectively. Then the half life of Th is .

Solution:

The correct answer is:

QUESTION: 4

The order of magnitude of the density of nuclear matter is :

Solution:

The correct answer is: **10 ^{17}**

QUESTION: 5

The value of binding energy for _{1}H^{2}, _{2}He^{4}, _{28}Fe^{56}, _{92}U^{235} are 2.22, 28.3, 492 and 1786 units respectively. The most stable nucleus is :

Solution:

The correct answer is: _{28}**Fe**^{56}

QUESTION: 6

The specific activity of radium is nearly

Solution:

The correct answer is: **1Ci**

QUESTION: 7

In equation _{92}U^{235} + _{0}n^{1 }→ _{56}Ba^{144} + _{36}Kr^{89} + X ; X is :

Solution:

The correct answer is: 3 _{0}**n**^{1}

Nuclear fission equation

_{92}U^{235 }+ _{0}n^{1 }→ _{56}Ba^{144} + _{36}Kr^{89} + 3 _{0}n^{1 }

Hence particle x is neutron.

QUESTION: 8

Masses of nucleus, neutron an protons are M, m_{n} and m_{p }respectively. If nucleus has been divided into neutrons and protons, then

Solution:

The correct answer is: M < (A - Z)m_{n} + Zm_{p}

QUESTION: 9

In most stable nuclei neutron number N and proton number Z has the relation

Solution:

The correct answer is: N ≥ Z

QUESTION: 10

The graph between the binding energy per nucleon (*E*) and atomic mass number (*A*) is as :

Solution:

The correct answer is:
