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:

A

`vecF_1` and `vecF_2` are action reaction pairs

B

`vecF_3` and `vecF_4` are action reaction pairs

C

`vecF_1 + vecF_2 = 0`

D

`vecF_3 + vecF_4 = 0`

Text Solution

Verified by Experts

The correct Answer is:
C, D
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`.
