1. An initially parallel cylindrical beam travels in a medium of refractive index µ(I) = µ02I, where µo and µ2 are positive constants and I is the intensity of the light beam. The intensity or the beam is decreasing with increasing radius.
The initial shape of the wavefront of the beam is 
A planar
B convex
C concave
D convex near the axis and concave near the periphery
2. An initially parallel cylindrical beam travels in a medium of refractive index µ(I) = µ02I, where µo and µ2 are positive constants and I is the intensity of the light beam. The intensity or the beam is decreasing with increasing radius.
The speed of light in the medium is........
A maximum on the axis of the beam
B minimum on the axis of the beam
C the same everywhere in the beam
D directly proportion to the intensety I
3. An initially parallel cylindrical beam travels in a medium of refractive index µ(I) = µ0+µ2I, where µo and µ2 are positive constants and I is the intensity of the light beam. The intensity or the beam is decreasing with increasing radius.
As the beam enters the medium, it will.....
A travel as a cylindrical beam
B diverge
C converge
D diverge near the axis and converge near the periphery
4.

A nucleus of mass M+∆m is at rest and decays into two daughter nuclei of equal mass m/2 each. Speed of light is c. 
The speed of daughter nuclei is,
 

A AIEEE_2010_question_paper_II_with_answer_on_testveda_test_veda_q4.1
B AIEEE_2010_question_paper_II_with_answer_on_testveda_test_veda_q4.2
C AIEEE_2010_question_paper_II_with_answer_on_testveda_test_veda_q4.3
D AIEEE_2010_question_paper_II_with_answer_on_testveda_test_veda_q4.4
5. A nucleus of mass M+∆m is at rest and decays into two daughter nuclei of equal mass m/2 each. Speed of light is c.
The binding energy per nucleon for the parent nucleus is E1and that for the daughter nuclei is E2. Then
A E1 = 2E2
B E2 = 2E1
C E1 > E2
D E2 > 2E1
