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
A
Both the scales read M/2 kg each
B
Both the scales read M kg each
C
The scale of the lower one reads M kg 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 kg
Answer
Both the scales read M kg each
Explanation
Solution
As the spring balance are massless therefore both the scales read M kg each.
