Two birds of exactly same mass are kept in two cages A and B. Cage A is made of glass and cage B is made of wire net. Both cages are kept on a weighting machine . While the birds are sitting on a bar fitted inside the cage the reading of the weighting machine is noted. If the birds now start flying and hovering in air in their cages , how do the readings in the weighting machine change.
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 kg) flies upward in the cage with an acceleration of 2 m/s2. The spring balance will now record a weight of
