Question

A bird is in a wire cage hanging from a spring balance. The reading of the balance is taken when the bird flying about in the cage, the when the bird is at rest in the cage. The first reading will be
a)much greater than the second
b)greater than the second
c)less than the second
d)same as the second

Answer 1

C) less then the cage

Answer 2

Heya!!

When the bird is flying in a wire cage, the air pressed by the wings of the bird will go out of cage, hence the spring balance will record less reading.

So, (C) less than the second is the correct answer
