Sample questions from recent papers

JEE Main 2024 · 8 Apr · Shift 2 · Motion on Rough Inclined Plane

A given object takes $\mathrm{n}$ times the time to slide down $45^{\circ}$ rough inclined plane as it takes the time to slide down an identical perfectly smooth $45^{\circ}$ inclined plane. The coefficient of kinetic friction between the object and the surface of inclined plane is :

(A) $1-\frac{1}{\mathrm{n}^2}$
(B) $\sqrt{1-\frac{1}{\mathrm{n}^2}}$
(C) $1-n^2$
(D) $\sqrt{1-n^2}$

Answer: (A)
