First slide

Friction on inclined plane of angle more than angle of repose

Question

The lengths of smooth & rough inclined planes of inclination 45° is same. Times of sliding of a body on two surfaces is t₁ ,t₂ and m = 0.75, then t₁ : t₂ =

Easy

A

2 : 1
B

2 : 3
C

1 : 2
D

3 : 2

Solution

$t_{smooth} = \sqrt{\frac{2 l}{gsin θ}}; t_{rough} = \sqrt{\frac{2 l}{g (\sin θ - μ_{k} \cos θ)}}$
