The mass of H2 molecule is 3.32 × 10-24 g If 1023 hydrogen molecules per second strike 2 cm2 of wall at an angle of 45° with the normal, while moving with a speed of105 cm/s, the pressure exerted on the wall is nearly.

Question

The mass of H2 molecule is 3.32 × 10-24 g If 1023 hydrogen molecules per second strike 2 cm2 of wall at an angle of 45° with the normal, while moving with a speed of105 cm/s, the pressure exerted on the wall is nearly. (A) 1350 N/m2 (B) 2350 N/m2 (C) 3320 N/m2  (D) 1660 N/m2

Tardigrade Admin · Accepted Answer

Correct answer is (b) 2350 N/m2

Q. The mass of $H_{2}$ molecule is $3.32 \times 1 0^{- 24} g$ If $1 0^{23}$ hydrogen molecules per second strike $2 c m^{2}$ of wall at an angle of $4 5^{\circ}$ with the normal, while moving with a speed of $1 0^{5} c m / s$ , the pressure exerted on the wall is nearly.

$1350 N / m^{2}$

$2350 N / m^{2}$

$3320 N / m^{2}$

$1660 N / m^{2}$

Correct answer is (b) $2350 N / m^{2}$
