  • Question 1
    4 / -1

    A block of mass M is pulled along a horizontal frictionless surface by a rope of mass m. If a force P is applied at the free end of the rope, the force exerted bythe rope on the block will be

  • Question 2
    4 / -1

    A rope of length L is pulled by a constant force F. What is the tension in the rope at a distance x from the end where the force is applied?

  • Question 3
    4 / -1

    Three equal weights A, B and C of mass 2 kg each are hanging on a string passing over a fixed frictional pulley as shown in the figure. The tension in the string connecting weights B and C is

  • Question 4
    4 / -1

    Two masses of 4 kg and 5 kg are connected by a string passing through a frictionless pulley and are kept on a frictionless table as shown in the figure. The acceleration of 5 kg mass is

  • Question 5
    4 / -1

    Two rectangular blocks A and B masses 2 kg and 3 kg respectively are connected by a spring of spring constant 10.8 Nm–1 and are placed on a frictionlesshorizontal surface. The block A was given an initial velocity of 0.15 ms-1 in the direction shown in the figure. The maximum compression of the spring duringthe motion is

  • Question 6
    4 / -1

    Three solids of masses m1, m2 and m3 are connected with weightless string in succession and are placed on a frictionless table. If the mass m3 is dragged with a force T, the tension in the string between m2 and m3 is

  • Question 7
    4 / -1

    Three blocks of masses m1, m2 and m3 are connected by massless strings as shown on a frictionless table. They are pulled with a force T3= 40 N . If m1. = 10 kg, m2 = 6 kg and m3 = 4 kg, the tension T2will be

  • Question 8
    4 / -1

    A 2 kg block is lying on a smooth table which is connected by a body of mass 1 kg by a string which passes through a pulley. The 1 kg mass is hanging vertically. The acceleration of block and tension in the string will be

  • Question 9
    4 / -1

    A block A of mass 7 kg is placed on a frictionless table. A thread tied to it passes over a frictionless pulley and carries a body B of mass 3 kg at the other end. The acceleration of the system is (given g = 10 ms–2)

  • Question 10
    4 / -1

    Three blocks of masses 2 kg, 3 kg and 5 kg are connected to each other with light string and are thenplaced on a frictionless surface as shown in the figure. The system is pulled by a force F =10 N, then tension T1is equal to
