By using the same ideas Show that the chemical potential can not exceed a limiting value to be determined, and give an expression for P0T), the pressure at this limit value. used to obtain the Fermi and Bose statistics, show that if the occupation number nǫ of an energy level ǫ is g

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
