Question

a block of mass 6kg is suspended through three massless spring balances as shown in the figure

Answer 1

Answer:

We have,

mass=4kg

So, Both the spring balance will give the same reading of 4kg

Let tension in the lower spring is T

1

Considering the equlibrium of the block T

1

=4g(reading)

T

1

=4kg

Let tension in the upper spring is T

2

Considering the equilibrium of the lower spring.T

2

will act into the upward direction and T

1

in the downward direction

T

2

−T

1

=0

T

2

−T

1

=4g (reading)

6

T

2

=4kg
