Question

A bird is sitting in a wire cage hanging from the spring balance. Let the reading of the spring balance be

W_{1}

.If the bird flies about inside the cage, the reading of the spring balance is

W_{2}

. Which of the following is true

Options:

A . W1=W2

B . W1>W2

C . W1

D . Nothing definite can be predicted

Answer: Option A
:
A
Again, the bird is not flying because of the spring force, or normal forse from the cage, right! So,

W_{1} = W_{2}
