A small mass slides down an inclined plane of inclination θ\theta with the horizontal. The coefficient of friction is μ=μ0x\mu = \mu_0 x , where xx is the distance through which the mass slides down and μ0\mu_0 a positive constant. Then the distance covered by the mass before it stops is a. 2μ0tan⁡θ\frac{2}{\mu_0} \tan \theta b. 4μ0tan⁡θ\frac{4}{\mu_0} \tan \theta c. 12μ0tan⁡θ\frac{1}{2\mu_0} \tan \theta d. 1μ0tan⁡θ\frac{1}{\mu_0} \tan \theta
