A light spring balance hangs from a hook of the other spring balance and a block of mass Mkg hangs from the former one. Then, which of the following is a true statement?

(a) Both the scales read Mkg each

(b) The scale of the lower one reads Mkg and of the upper one zero

(c) The reading of the two scales can be anything but the sum of the readings will be Mkg

(d) Both the scales read M/2 kg

The question was posed to me by my college director while I was bunking the class.

The origin of the question is Laws of Nature in division Laws of Motion of Engineering Physics I
