Question 1
A powder comprising particles of various sizes is stirred up in a vessel filled to a height of 10 cm with water. Assuming the particles to be spherical, find the size of the largest particle that will remain in suspension after 1 h (density of powder = 4 , viscosity of water = 0.01 poise). Question 2
Assertion :Dust particles generally settle down in a closed room.Reason :The terminal velocity is inversely proportional to the square of their radii.
