A bird is sitting in a large closed cage...

A bird is sitting in a large closed cage which is placed on a spring balance. It records a weight of 25 N. The bird (mass=0.5 kg) flies upward in the cage with an acceleration of `2m//s^(2)`. The spring balance will now record a weight of :-

A

24 N

B

25 N

C

26 N

D

27N

Text Solution

Verified by Experts

The correct Answer is:
C
Reading = weight of cage + Reaction of bird
` = 20 + 0.5 (10+2) = 26 N`
