Model Questions for Entrance Examination

Full Marks : 100 Time : 2 hours

Syllabus: B.Sc. Physics (Honours) syllabus of any Indian University Entrance test has two parts, Part A and Part B of 50 marks each and is of a total duration of 2 hours.

Part A consists of 50 objective type questions of one mark each. Duration for this part is one hour.
Part B consists of short descriptive type questions to examine the conceptual clarity and reasoning ability of the candidate. The candidate is required to attempt any 5 questions of 10 marks each out of about 10 given questions.

Typical questions for Part A and Part B are given below:

PART – A

Excitons are

(a) excited electrons in pairs (b) neutron-proton pairs

Hamiltonian formalism is easier to handle than Lagrangian formalism because Hamiltonian formalism involves

(a) first order differential equations

(b) generalized momentum instead of generalized co-ordinates

(d) no time derivatives

An electric potential field is produced by joint charges 1 mC and 4 mC located at (-2, 1, 5) and (1, 3, -1) respectively. The energy stored in the field is

(a) 2.57 mJ (b) 5.14 mJ

Which of the following potentials does not satisfy the Laplace’s equation?

(a) V = 2x + 5 (b) V = 10 xy

The expression which implies the nonexistence of magnetic monopoles is

(a) Ñ x E = -¶B/¶t (b) Ñ.B = 0

PART – B

Starting from the Langragian equation, prove that the equation of motion a simple pendulum is .. g θ + — sin θ = 0 l

where θ, g and 1 are angular displacement, acceleration due to gravity and length of the string respectively.

Find the energy release, if two ₁H² nuclei fuse together to form ₂He⁴ nucleus where the binding energies per nucleon of ₁H² and ₂He⁴ are 1.1 MeV and 7.0 MeV respectively.
The electrostatic potential due to a certain charge distribution is given by the expression :

V(x, y, z) = – (x2yz + xy2z + xyz2) volts

Calculate the electric field and charge density at the point (2, 1, 3)

A half wave rectifier uses load resistor RL = 8kW and shunt filter capacitor of 12mF. The sinusoidal input voltage is 20sin2p50t. The angle of conduction is 400. Assuming the rectifier to be ideal (Rf = 0, Rp = ¥) calculate :

1) dc load current Idc

2) dc output voltage Vdc

3) ripple voltage VR

4) ripple factor y (cos 400 = 0.7660)

(i) Explain which of the following nuclear reactions are allowed or forbidden.

(a) 0n1®1p1+-1e0+ve

(b) 0n1®1p1+-1e0+ve

(ii) Draw the energy level diagram showing anomalous Zeeman effect. Can it be explained by classical theory ? Explain.
