  1. Remain unchanged
  2. Decreases in divergence
  3. Increases in divergence
  4. Gains a positive charge
Sample 2 · Atomic and nuclear physics

  1. 3
  2. 24
  3. 72
  4. 96
Sample 3 · Mechanics: motion, forces, work and energy

A razor blade is observed to be used to cut a piece of cloth with more ease than with a knife. This could be explained most precisely by:

  1. small area of contact and small force exerted
  2. high pressure and high force exerted
  3. small area of contact and high pressure exerted
  4. small force and low pressure exerted
Sample 4 · Waves, light and sound

The paper rider is thrown off when:

  1. the string is vibrating at the same frequency as the tuning fork
  2. the paper rider is vibrating at the frequency as the tuning fork
  3. when the natural frequency of the string is different from that of the tuning fork
  4. when the string produces a node were the paper rider is
Sample 5 · Heat and thermal physics

During the night the temperature of the sea water is higher than that of the sandy sea shore. This is because sea water:

  1. is a better absorber of heat than sand
  2. is a poorer radiator of heat than sand
  3. has a higher heat capacity than sand
  4. has a lower heat capacity than sand
