  • Question 1
    4 / -1
    If a simple pendulum is taken to place where g decrease by 2%, then the time period
    Solution

  • Question 2
    4 / -1
    A mass M is suspended by two springs which are connected in series as shown in the Figure. If the spring constants are k1 and k2, then time period of vertical vibration is

    Solution

  • Question 3
    4 / -1
    An object suspended from a spring exhibits oscillations of period T. Now the spring is cut in two halves and the same object is suspended with two halves as shown in fig. The new time period of oscillation will become

    Solution

  • Question 4
    4 / -1
    Two blocks with masses m1 = 1 kg and m2 = 2 kg are connected by a spring of spring constant k = 24 N/m and placed on a frictionless horizontal surface. The block m1 is imparted an initial velocity v0 = 12 cm/s to the right, the amplitude of oscillation is

    Solution

  • Question 5
    4 / -1
    Particle of mass m is executing oscillations about the origin on the x – axis with amplitude A. its P.E. is given as U(x) = a x4, where α is positive constant. The x – coordinate of mass where potential energy is one third of the K.E. of particle, is
    Solution

  • Question 6
    4 / -1
    For a simple pendulum the graph between g and T2 will be
    Solution

  • Question 7
    4 / -1
    If a simple pendulum is taken to a place where g decrease by 2%, then the time period
    Solution

  • Question 8
    4 / -1

  • Question 9
    4 / -1
    A tunnel is made across the earth of radius R, passing through its centre. A ball is dropped from a height h in the tunnel. The motion will be periodic with time period.

    Solution

  • Question 10
    4 / -1
    A and B are fixed points and the mass M is tied by straight at A and B. If the mass M is displaced slightly out of this plane and released, it will execute oscillation with period
    (Given AM = BM = L, AB = 2d)
