Question:

A light spring balance hangs from the hook of the other light spring balance and a block of mass $M \mathrm{~kg}$ hangs from the former one. Then the true statement about the scale reading is

  1. both the scales read $M \mathrm{~kg}$ each

  2. the scale of the lower one reads $M \mathrm{~kg}$ and of the upper one zero

  3. the reading of the two scales can be anything but the sum of the reading will be $M \mathrm{~kg}$

  4. both the scales read $M / 2 \mathrm{~kg}$ each
