Molecule of a gas in a container hits on...

Molecule of a gas in a container hits one wall (1) normally and rebounds back. It suffers number of collision and hits the opposite wall (2) which is at angle of `30^(@)` with wall 1. Assuming the collision to be elastic and the small collision time to be the same for both the walls. The magnitude of average force by walls and 2 are `F_(1)` and `F_(2)` provide to molecule during collision satisfy

A

`F_(1) gt F_(2)`

B

`F_(1) lt F_(2)`

C

`F_(1)=F_(2)` both non zero

D

`F_(12)F_(220)`

Text Solution

Verified by Experts

The correct Answer is:
A
`F_(1) = (2mv)/(Deltat)" " F_(2)= (2mvcos30^(@))/(Deltat)`
Hence `F_(1) gt F_(2)`
