Q5: The mass of a hydrogen molecule is 3.32 × 10–27/ kg. If 1023 hydrogen molecules strike, per second, a fixed wall of area 2 cm2 at an angle of 45° to the normal, and rebound elastically with a speed of 103 m s–1, then the pressure on the wall is nearly (a) 2.35 × 103 N m–2 (b) 4.70 × 103 N m–2 (c) 2.35 × 102 N m–2 (d) 4.70 × 102 N m–2
