Question

A light spring balance hangs from the hook of the
other light spring balance and a block of mass Mkg
hangs from the former one. Then the true statement
about the scale reading is
Both the scales read M/2 kg each
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 reading will be Mkg​

Answer 1

Answer:

Equilibrium of Concurrent Forces-

If all the forces working on the body are acting on the same point then they are said to be concurrent.

where,

∑

F

net

=0

∑

y

F

=0

Three forces will be in equilibrium if they are represented by three sides of triangle taken in order.

Hence, both the scales read M kg each

So, the option A is the correct answer.
