A cylindrical vessel filled with water is released on an inclined surface of angle $\theta$ as shown in figure.The friction coefficient of surface with vessel is $\mu( < \tan \theta)$.Then the contact angle made by the surface of water with the incline will be

A

$\tan ^{-1} \mu$

B

$\theta-\tan ^{-1} \mu$

C

$\theta+\tan ^{-1} \mu$

D

$\cot ^{-1} \mu$

Solution

(a)

Figure shows forces acting on a particle on the surface, with respect to vessel.
