Question

+
3. A block of mass 10 kg is suspended through two light
spring balances as shown in figure.
1) Both the scales will read 10 kg.
2) Both the scales will read 5 kg.
3) The upper scale will read 10 kg and the lower zero.
4) The readings may be anything but their sum will he 10 kg.
10 kg

Answer 1

Answer:

1) Both the scales will read 10 kg.

Explanation:

Answer 2

Answer:

Both the scales will read 10Kg

Explanation:

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

⇒ T 1 = 10kg ; and

T 1 = 10kg ; and ⇒ T2 = T 1

T 1 = 10kg ; and ⇒ T2 = T 1⇒ T = T2 = 10 kg ;

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