A block of mass m is kept on an inclined plane of a lift moving down with acceleration of \(2 m s^{-2}\). What should be the coefficient of friction to let the block move down with constant velocity relative to lift:
- \(\mu=\frac{1}{\sqrt{3}}\)
- \(\mu=0,4\)
- \(\mu=0,8\)
- \(\mu=\frac{\sqrt{3}}{2}\)
Answer
(A) = 1 3
