•  Both of the above
•  None of these

Only nuclear attractive

Q7. Outside a nucleus

•  Neutron is stable
•  Proton and neutron both are stable
•  Neutron is unstable
•   Neither neutron nor proton is stable

Neutron is unstable

Q8.  Nuclear force is

•  Isobars
•  Isoclinics

Isotones

Q10. Two nuclei are said to be mirror nuclei if

•  Number of protons in the two nuclei are equal
•  Number of neutrons in the two are equal
•  Number of neutrons in one equals number of protons in the other and vice-versa
•  The number of nucleons in the two are equal

Number of neutrons in one equals number of protons in the other and vice-versa
