The mass of hydrogen molecule is `3.32xx10^(-27)` kg. If `10^(23)` hydrogen molecules strick per second at 2 `cm^(2)` area of a rigid wall at an angle of `45^(@)` from the normal and rebound back with a speed of 1000 `ms^(-1)`, then the pressure exerted on the wall is

`2.35xx10^3N/m^2`

`4.70xx10^3N/m^2`

`2.35xx10^2N/m^2`

`4.70xx10^2N/m^2`
