Question

A bird weighs 2 k g and is inside a closed cage of 1 k g . If it starts flying with constant velocity, then what is the weight of the bird and cage assembly, 1.5 k g, 2.5 k g, 3 k g, 4 k g

MARKS App · Accepted Answer

When the bird flies, it pushes air down to balance its weight. So the weight of the bird and closed cage assembly remains unchanged.
