A block is kept on an inclined plane of inclination \( \theta \) of length 1. The velocity of particle at the bottom of inclined plane is (the coefficient of friction is \( \mu \) )
(a) \( \sqrt{2 g l(\mu \cos \theta-\sin \theta)} \)
(b) \( \sqrt{2 g l(\sin \theta-\mu \cos \theta)} \)
(c) \( \sqrt{2 g l(\sin \theta+\mu \cos \theta)} \)
(d) \( \sqrt{2 g l(\cos \theta+\mu \sin \theta)} \)
