Question1. Ionization potential of hydrogen atom is 13.6 eV. Hydrogen atoms in the ground state are excited by monochromatic radiation of photon energy 12.1 eV. According to Bohr’s theory, the spectral lines emitted by hydrogen will be:

  • Two
  • Three
  • Four
  • One

Question2. A microscope is focused on a mark on a piece of paper and then a slab of glass of thickness 3 cm and refractive index 1.5 is placed over the mark. How should the microscope be moved to get the mark in focus again?

1) 1 cm upward

2) 0.5 cm downward

3) 1 cm downward

4) 0.5 cm upward

Question3. In a discharge tube ionization of enclosed gas is produced due to collisions between:

1) Positive ions and neutral atoms/molecules

2) Negative electrons and neutral atoms/molecules

3) Photons and neutral atoms/molecules

4) Neutral gas atoms/molecules

Question4. A parallel plate air capacitor is charged to a potential difference of V volts. After disconnecting the charging battery the distance between the plates of the capacitor is increased using an insulating handle. As a result the potential difference between the plates:

1) Decreases

2) Does not change

3) Becomes zero

4) Increases

Question5. Two common characters found in centipede, cockroach and crab are

1) Compound eyes and anal cerci

2) Jointed legs and chitinous exoskeleton

3) Green gland and tracheae

4) Book lungs and antennae

Question6. Antiparallel strands of a DNA molecule means that:

1) One strand turns anti-clockwise

2) The phosphate groups of two DNA strands, at their ends, share the same position

3) The phosphate groups at the start of two DNA strands are in opposite position (pole)

4) One strand turns clockwise

Question7. People living at sea level have around 5 million RBC per cubic millimeter of their blood whereas those living at an altitude of 5400 metres have around 8 million. This is because at high altitude

1) People get pollution-free air to breathe and more oxygen is available

2) Atmospheric O2 level is less and hence more RBCs are needed to absorb the required amount of O2 to survive

3) There is more UV radiation which enhances RBC production

4) People eat more nutritive food, therefore more RBCs are formed
