A body takes time $t$ to reach the bottom of an inclined plane of angle $θ$ with the horizontal. If the plane is made rough, time taken now is $2 t$ . The coefficient of friction of the rough surface is

Options:

Answer:

Solution:

$μ = \tan θ (1 - \frac{1}{n^{2}})$ $= \tan θ (1 - \frac{1}{2^{2}}) = \frac{3}{4} \tan θ$
