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 $\mathrm{M} \mathrm{kg}$ each
  2. The scale of the lower one reads $\mathrm{M} \mathrm{kg}$ and of the upper one zero
  3. The reading of the two scales can be anything but the sum of the reading will be $\mathrm{M} \mathrm{kg}$
  4. Both the scales read $\mathrm{M} / 2 \mathrm{~kg}$ each
