In the figure shown, a balloon is pressed against a wall. It is in equilibrium and maximum compressed state.
`vecF=` force of balloon on hand of man, `vecF_2=` force of balloon on wall,`vecF_3=` friction,`vecF_4=` weight of balloon. Which of the following statements are correct:

Answer

C, D

Explanation

Consider the F.B.D of balloon net force on balloon is zero. So
`vecF_3+vecF_4=0`
`-vecF_1-vecF_2=0impliesvecF_1+vecF_2=0`
`vecF_1` and `vecF_2` can't be action-reaction pair because they do not act between the same two bodies. Similarly for `vecF_3` and `vecF_4`.
