1. The problem statement, all variables and given/known data Consider a spherical particle immersed in water. It will experience random collisions with the surrounding water molecules. Suppose there are such water molecules around the particle. Half (n/2) of the water molecules will push the particle to the right and the other half to the left. On average, this “collision force” (force arising from collisions) vanishes. Does this mean that the particle will not be driven to the right or to the left? 2. Relevant equations not sure 3. The attempt at a solutiIn I know the particle will move. But I am not sure how to explain that using equations.
