Physics

In a thought experiment, a cubic box of side length 0.01 mmcontains three particles. One particle moves just in thex-direction, colliding elastically with the left and right walls ofthe cube. The second atom moves just in the y-direction, collidingelastically with the front and back walls of the cube. The thirdatom moves just in the z-direction, colliding elastically with thetop and bottom walls of the cube. All three atoms have speed 500m/s and mass 6.7x10-27 kg. What is the average pressure in thebox?
A. 1.7 Ã— 10-3 Pa
B. 1.7 Ã— 10-6 Pa
C. 3.3 Ã— 10-3 Pa
D. 5.0 Ã— 10-6 Pa
E. 1.01 Ã— 10-5 Pa
F. 3.10 x 10-5 Pa
