A uniform circular disc of radius R is placed on a frictionless horizontal plane. Another identical disc rotating with velocity omega_(0) is gently placed on top the first disc.The coefficient of friction between the discs is mu. The time in which both disc acquire same angular velocity is nRomega_(0)//8mu g. Find the value of n.
