Question

A light spring balance hangs from the hook of the other light spring balance and a block of mass A/kilogram hangs from the former one. Which of the following statements about the scale reading is true? (A) Both the scales read M /2 kilogram each (B) Both the scales read M kilogram each (C) The scale of the lower one reads M/kilogram and of the upper one zero (D) The reading of the two scales can be anything but the sum of the reading will be M kilogram

Q. A light spring balance hangs from the hook of the other light spring balance and a block of mass A/kilogram hangs from the former one. Which of the following statements about the scale reading is true?

Both the scales read $M /2$ kilogram each

Both the scales read $M$ kilogram each

The scale of the lower one reads $M$ /kilogram and of the upper one zero

The reading of the two scales can be anything but the sum of the reading will be $M$ kilogram

The springs are connected in series and the spring balance are massless therefore both the scales read M kg each
