Reading = Weight of cage + Reaction by bird =20+0.5(10+2)=26 N

Q. 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 $m = 0.5 k g$ ) flies upward in the cage with an acceleration of $2 m / s^{2}$ . The spring balance will now record a weight of

24 N

25 N

26 N

27 N

Reading $=$ Weight of cage $+$ Reaction by bird
$= 20 + 0.5 (10 + 2) = 26 N$
