Q2. A BIRD IS SITTING ON THE FLOOR OF A GLASS CAGE. SUDDENLY IT STARTS FLYING INSIDE THE CAGE. WILL THE BOY HANDLING IT EXPERIENCE MORE WEIGHT OR LESS WEIGHT? 
THE LOGIC & DIFFERENCE B/W WIRE & GLASS CAGE? 

Answers :

1) Girl experiences less weight  when bird statrts flying in the cage. in the cage the bird exerts the force on the rods as well as on the base of the cage. the total force is not equal its wieght because force disperse between rods of cage.so girl experiences less weight. 


2) in the boy case the force dispersion is not occuring. the glass cage experiences the total force which is equal to its weight.

so u can say that boy experiences same weight after bird is start flying.
