A light spring balance hangs from the hook of the other light spring balance and a block of mass M kg hangs from the former one. Then the true statement about the scale reading is-

  1. both the scales read M kg each
  2. the scale of the lower one reads M kg and of the upper one zero
  3. The reading of the two scales can be anything but the sum of the readings will be M kg
  4. both the scales read M/2 kg

The correct answer is: both the scales read M kg each
