Question

A block of mass $10Kg$ is suspended through two light spring balances as shown in figure.

• A. Both the scales will read $10Kg$
• B. Both the scales will read $5Kg$
• C. The upper scale will read $10Kg$ and the lower zero
• D. The readings may be anything but their sum will be $10Kg$

Answer 1

The correct option is A Both the scales will read $10Kg$

Since the block and the balances are in equilibrium and considering that balances are massless.

$\Rightarrow T_1=10kg$ and

$T_2=T_1$

$\Rightarrow T_{=}{T}_2=10kg$

and, hence, both the balances will read 10kg.
