engineering recuitment NCL Assistant Foreman (Trainee) Mock Test 2024 Engineering Mechanics Equilibrium and Friction Friction
A block of mass m slides down an inclined plane (co-efficient of friction = μ) from the rest as in figure. What will be the velocity of block when it reaches the lowest point of plane?
1
2gh(1 - μcot θ)
2
\(\sqrt{2gh(1~-~\mu \cot \theta)}\)
3
\(\sqrt{2gh\mu(1~-~\cot \theta)}\)
4
\(\sqrt{2gh(1~-~\mu \sin \theta)}\)
