A block is kept on an inclined plane of inclination $$\theta$$ of length l. the velocity of particle at the bottom of inclined is (the coefficient of friciton is $$\mu$$)
(A) $$\sqrt{{{2}{g}{l}{\left(\mu{\cos{\theta}}-{\sin{\theta}}\right)}}}$$
(B) $$\sqrt{{{2}{g}{l}{\left({\sin{\theta}}-\mu{\cos{\theta}}\right)}}}$$
(C) $$\sqrt{{{2}{g}{l}{\left({\sin{\theta}}+\mu{\cos{\theta}}\right)}}}$$
(D) $$\sqrt{{{2}{g}{l}{\left({\cos{\theta}}+\mu{\sin{\theta}}\right)}}}$$
