For Questions 13 to 16, two statements are given –one labelled Assertion (A) and the other labelled
Reason (R). Select the correct answer to these questions from the options given below.
A. If both Assertion and Reason are true and Reason is the correct explanation of Assertion.
B. If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
C. If Assertion is true but Reason is false.
D. If both Assertion and Reason are false.

13. Assertion (A): On increasing the current sensitivity of a galvanometer by increasing the number of
turns may not necessarily increase its voltage sensitivity.
Reason(R): The resistance of the coil of the galvanometer increases on increasing the number of
turns.

14. Assertion (A): In a hydrogen atom there is only one electron but its emission spectrum shows many
lines.
Reason (R): In a given sample of hydrogen there are many atoms each containing one electron;
hence many electrons in different atoms may be in different orbits so many transitions from higher
to lower orbits are possible. 

15. Assertion (A): Nuclei having a mass number of about 60 are the least stable.
Reason (R): When two or more light nuclei are combined into a heavier nucleus then the binding
energy per nucleon will decrease.

16. Assertion (A): de Broglie's wavelength of a freely falling body keeps decreasing with time.
Reason (R): The momentum of the freely falling body increases with time.
