A block of 3 kg rests in limiting equilibrium on an inclined plane of inclination 30. If the plane is raised to an inclination 60∘, the force along the plane required to support it is A block of 3 kg rests in limiting equilibrium on an inclined plane of inclination 30. If the plane is [...]

A body of mass 10 kg is lying on a rough plane inclined at an angle of 300 to the horizontal and the co-efficient of friction is 0.5. The minimum force required to pull the body up the plane is ( g = 9.8 m/s2). The acceleration of the block is 1) 6 m/s^2 2) [...]

A lift is moving downwards with an acceleration equal to the g, acceleration due to gravity. A body of mass m kept on the floor of the lift is pulled horizontally. If the coefficient of friction is μ, then the friction resistance offered acting on the block is: A lift is moving downwards with an [...]
