1.	A smooth block is released from rest on a 45^(@) inclined plane and it slides a distance 'd'. The time taken to slide is n times that on a smooth inclined plane. The coefficient of friction
Answer» `mu_(k)=1-(1)/(n^(2))` `mu_(k)=sqrt(1-(1)/(n^(2)))` `mu_(k)=(1)/(1-n^(2))` `mu_(k)=sqrt((1)/(1-n^(2)))` SOLUTION :`mu_(k)=tan THETA(1-(1)/(n^(2)))`
