Default Re: Nalanda Open University Exam Paper

I am here by providing you the question paper of last year of the B.SC Physics part 1 paper of the Nalanda Open University

I am here by providing you the few question list asked in the last exam.
Group-A

1. Define Gradient of a scalar, divergence and Curl of a vector. How do you express these quantities in Cartesian and spherical Polar Coordinates?
2. Distinguish between holonomic and non-holonomic constraints. Give suitable examples for each. What are generalised coordinates? What is the advantage of using these Coordinates for a physical system.
3. Set up the Lagrangian for a (i) one dimensional harmonic oscillator & (ii) particle of mass m falling freely in uniform gravitational field. Write equations of motion in each case using Lagrange's equations.
4. Derive the expression for force experienced by a particle in rotating frame of reference and hence define the 'centrifugal force' and 'Coriolis force'.
5. Write notes on any two of the following:
(a) Kepler's laws (b) D 'Alembert's principle (c) Hamilton's Equations of Motion

Nalanda Open University
Annual Examination - 2012

B.Sc. Physics (Honours), Part-I
Paper-I
Time: 3.00 Hrs. Full Marks: 80
Answer any five questions, selecting at least one from each group.
All questions carry equal marks.

Group-A
1. Define Gradient of a scalar, divergence and Curl of a vector. How do you express these
quantities in Cartesian and spherical Polar Coordinates ?
2. Distinguish between holonomic and non-holonomic constraints. Give suitable examples
for each.
What are generalised coordinates? What is the advantage of using these
Coordinates for a physical system.
3. Set up the Lagrangian for a (i) one dimensional harmonic oscillator & (ii) particle of
mass m falling freely in uniform gravitational field. Write equations of motion in each
case using Lagrange's equations.
4. Derive the expression for force experienced by a particle in rotating frame of reference
and hence define the 'centrifugal force' and 'Coriolis force'.
5. Write notes on any two of the following:
(a) Kepler's laws (b) D 'Alembert's principle (c) Hamilton's Equations of
Motion

Group-B
6. Describe with a neat diagram, the Midrelson-Morley Experiment and explain clearly the
conclusions drawn from this experiment.
7. State and explain Lorentz Transformation Equations and use them to obtain rule for
transformation of velocity of a particle. Prove that velocity of light is in variant under
L.T.
8. Establish the following equations for a relativistic system.
(a) K c m K

where the symbols have the usual meaning.

Group-C
9. Determine the position of nodes and antinodes in the formation of stationary waves.
10. What are ultrasonic Waves? How are they produced? Mention its properties.
