  • Question 1/10
    4 / -1

    Solutions

  • Question 2/10
    4 / -1
    A simple pendulum is released from A, as shown in the figure. If m and l represent the mass of the bob and length of the pendulum, the gain kinetic energy at B is

    Solutions

  • Question 3/10
    4 / -1
    A mass of 2.0 kg is put on a flat pan attached to a vertical spring fixed on the ground as shown in the figure. The mass of the spring and the pan is negligible. When pressed slightly and released the mass executes a simple harmonic motion. The spring constant is 200 Nm-1. What should be the minimum amplitude of the motion, so that the mass gets detached from the pan? (take, g = 10ms-2)

    Solutions

  • Question 4/10
    4 / -1
    A uniform spring of force constant k is cut into two pieces whose lengths are in the ratio of 1:2. What is the force constant of second piece in terms of k?

    Solutions

  • Question 6/10
    4 / -1
    What is the velocity of the bob of a simple pendulum at its mean position, if it is able to rise to vertical height of 10 cm? (take, g = 9. 8 ms-2)

    Solutions

  • Question 7/10
    4 / -1
    The pendulum bob has a speed of 3 ms-1 at its lowest position. The pendulum is 0.5 m long. The speed of the bob, when the length makes an angle of 60° to the vertical will be (take, g =10 ms-2)
