A given object takes n times more time to slide down a 45° rough inclined plane as it takes to slide down a perfectly smooth 45° incline. The coefficient of kinetic friction between the object and the incline Is: 
  • a)
  • b)
  • c)
  • d)
Correct answer is option 'A'. Can you explain this answer?

So

Sin θ = n2 sinθ − µn2 cosθ
1 = n2 − µn2
1 − n2 = −µn2
n2 − 1 = −µn2
µ = 1 − 1/n2
