Questions (page 2)

Q1.

(a) Q1. Solve any five out of seven. (8×5=40) What is linear momentum? State the principle of conservation of linear momentum. Explain the principle using an example.

(b) Define the term interference. Show that in Young's double slit experiment, bright and dark bands are equally spaced.

(c) What qualifies a material to be called as a dielectric ? How do you define the dielectric constant of a given material ? What happens when such material is kept in an electric field?

(d) Discuss the following with neat diagrams, i) Self-inductance. ii) Mutual-inductance.

(e) Define the following and show on an indicator diagram, i) Isothermal process ii) Adiabatic process iii) Isobaric process iv) Isochoric process.
(f) What is a blackbody? Describe the characteristics of blackbody radiation with the help of a neat diagram. Give examples of blackbody.
(g) Describe the structure of a typical optical fibre. Differentiate between step-index and graded index fibre.

Q2.

(a) Q2. Obtain the moment of inertia of a solid, uniform sphere about an axis through its center. Calculate the moment of inertia of a solid sphere of mass kg and radius 0.5 m, rotating about an axis 0.2 m from the centre.

(b) Discuss the Fraunhofer diffraction at a circular aperture and obtain the radius of Airy's disc. In Fraunhofer diffraction pattern due to a circular aperture, the screen is at a distance of 1.5 m from the convex lens. The aperture is illuminated by sodium light of wavelength 5893 Å. If the diameter of the aperture is 0.2 mm, find the separation between the central disc and the first minimum.

(c) Write down the Poisson and Laplace equations in electrostatics.
(C) Use Laplace law to compute the potential outside a sphere of uniform charge density 'ρ' at a distance 'r'.
