	A 0.8-gram package lying on a horizontal surface is attached to a horizontal string which passes over a smooth pulley. When a mass of 0.0006 KG is attached to the other end of the string, the package is on the point of moving. Find μ, the coefficient of friction and also define the friction and it’s any two types with at least one relevant example of each which are used in the
