Question Paper
Nalanda Open University
Annual Examination 2016
B.Sc. Physics (Honours), Part-II
Paper-IV (Electrostatics, Magnetism current Electricity and Modern Physics)
Time: 3.00 Hrs. Full Marks: 80
Answer any five questions. All questions carry equal marks.
1. Define a quadrupole. Calculate the field and potential at a point far away
from a linear quadrupole.
2. Describe Weiss' theory of ferromagnetism. Discuss the temperature
dependence of spontaneous magnetization.
3. Give the principle and working of De Sauty's bridge using necessary
diagrams.
4. Define Thomson and Petlier Coefficient. Show that, in a thermocouple AB,
the total emf is given by 2
1 E dT A B
T
T Where symbols have their
usual meaning.
5. Describe the Millikan's oil drop experiment to find the charge on an
electron.
6. Obtain the resonance frequency of parallel resonant circuit. Discuss the
sharpness of resonance of the circuit.
7. Discuss the growth of charge and current in an LCR circuit when a direct
e.m.f. is applied to it.
8. Give an account of Heisenberg's uncertainty principle. Outline an idealized
experiment to bring out its significance.
9. State and explain Compton effect. How do you experimentally find the
change in wave-length by Compton Effect?
10. What is Einstein's quantum Hypothesis and write down photo electric
equation. Calculate the work function of sodium light in electron volt. Given
that the threshold Wavelength is 6800
A and h 6.625 x 10-34 JS-1
