A given object takes n times more time to slide down 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
- \(\frac{1}{2-n^{2}}\)
- \(1-\frac{1}{n^{2}}\)
- \(\sqrt{1-\frac{1}{n^{2}}}\)
- \(\sqrt{\frac{1}{1-n^{2}}}\)
Answer
(B) 1- 1 n^ 2
