    A mass of 10 kg is suspended vertically by a rope from the roof. When a horizontal force is applied on the rope at some point, the rope deviated at an angle of 45^(@) at the roof point. If the suspended mass is at equilibrium, the magnitude of the force applied is (g =10 ms^(-2) )

    A man is pulling a rope attached to a block on a smooth horizontal table. The tension in the rope will be the same at all points

    Two particles of equal mass are connected to a rope AB of negligible mass, such that one is at end A and the other dividing the length of the rope in the ratio 1:2 from A.The rope is rotated about end B is a horizontal plane. Ratio of the tensions in the smaller part to the other is (ignore effect of gravity)

    A mass of 20 kg is suspended by a rope of length 4 m from the ceiling. A force of 60 N is applied at the midpoint of the rope in the horizontal direction. What is the angle made by the rope with the vertical in equilibrium? Assume that the mass of the rope is negligible and g=10m//s^(2)

    In order to raise a mass of 100kg a of mass 60kg fastens a rope to it and passes the rope over a smooth pulley. He climbs the rope with acceleration 5g//4 relative to the rope. The tension in the rope is: Take g=10m//s^(2)
