Question

In Fig. 4.148 a balloon is pressed against a wall. It is in equilibrium and maximum compressed state.
$_{1}$ = force of balloon on hand of man; $_{2}$ = force of balloon on wall; $_{3}$ = friction; $_{4}$ = weight of balloon. Consider the following statements:

A

_{1}

and

_{2}

are action reaction pairs.
