The mass of a hydrogen molecule is `3.32xx10^(-27)` kg. If `10^(23)` hydrogen molecules strike, per second, a fixed wall of area `2" cm"^(2)` at an angle of `45^(@)` to the normal and rebound elastically with a speed of `10^(3)" m"//"s"`, then the pressure on the wall is nearly:

A

`2.35 xx 10^2 N//m^2`

B

`4.70 xx 10^2 N//m^2`

C

`2.35 xx 10^3 N//m^2`

D

`4.70 xx 10^3 N//m^2`
