Q. 1. This question contains Statement-1 and Statement -2. Of the four choices given after the statements, choose the one that best describes the two statements.

Statement - 1: Energy is released when heavy nuclei undergo fission or light nuclei undergo fusion. and

Statement - 2: For heavy nuclei, binding energy per nucleon increases with increasing Z while for light nuclei it decreases with increasing Z.

  1. Statement - 1 is true, Statement- 2 is true; Statement -2 is not a correct explanation for Statement-1
  2. Statement - 1 is true, Statement- 2 is false
  3. Statement - 1 is false, Statement- 2 is true

Sol: Correct answer is (2)

Q. 2. This question contains Statement-1 and Statement -2. Of the four choices given after the statements, choose the one that best describes the two statements.

Statement - 1: For a mass M kept at the centre of a cube of side „a‟ the flux of gravitational field passing through its sides is and

Statement - 2: If the direction of a field due to a point source is radial and its dependence on the distance 'r' from the source is given as , its flux through a closed surface depends only on the strength of the source enclosed by the surface and not on the size or shape of the surface.

  1. Statement - 1 is true, Statement- 2 is true; Statement -2 is not a correct explanation for Statement-1
  2. Statement - 1 is true, Statement- 2 is false

Q. 3. Two full turns of the circular scale of a screw gauge cover a distance of 1 mm on its main scale. The total number of divisions on circular scale is 50. Further, it is found that screw gauge has a zero error of - 0.03mm. While measuring the diameter of a thin wire, a student notes the main scale reading of 3mm and the number of circular scale divisions in line with the main scale as 35. The diameter of wire is

  1. 3.67 mm
  2. 3.38 mm
  3. 3.32 mm
  4. 3.73 mm

Sol:
