A molecule of gas in a container hits one wall (1) normally and rebounds back. It suffers no collision and hits the opposite wall (2) which is at an angle of $30^o$ with wall 1.
Assuming the collisions to be elastic and the small collision time to be the same for both the walls, the magnitude of average force by wall 2. $(F _2)$ provided the molecule during collision satisfy

  1. $F _1 > F _2$
  2. $F _1 < F _2$
  3. $F _1=F _2$, both non-zero
  4. $F _1=F _2=0$
