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