  • Question 1/10
    1 / -0

    A ring of radius R is hung by a nail on its periphery such that it can freely rotate in its vertical plane. The time period of the ring for small oscillations is:

    Solutions

     

  • Question 2/10
    1 / -0

    In a stationary lift a spring-block system oscillates with a frequency f. When the lift accelerates up the frequency becomes f', then 

    Solutions

    The time period of the spring-block system does not depend on the effective acceleration due to gravity. So, the frequency also does not depend and remains the same.

     

  • Question 3/10
    1 / -0

    The equation of a SHM is given as x = 5 sin(4πt + π/3), where t is in seconds and x in meters. During a complete cycle, the average speed of the oscillator is:

    Solutions

     

  • Question 4/10
    1 / -0

    If a simple pendulum is brought deep inside a mine from earth surface, its time period of oscillation will 

    Solutions

    As the effective acceleration due to gravity decreases, the time period of oscillations of the simple pendulum increases.

     

  • Question 5/10
    1 / -0

    The initial phase of the particle executing SHM with y = 4 sin ωt + 3 cos ωt is 

    Solutions

     

  • Question 6/10
    1 / -0

    Two simple harmonic motions are represented by y1 = 6 sin ( 2πt + π/3) and y2 = 3(sin 2πt + cos 2πt). The ratio of their amplitudes is

    Solutions

     

  • Question 7/10
    1 / -0

    The graph between velocity and acceleration of a particle executing S.H.M. can be

    Solutions

     

  • Question 8/10
    1 / -0

     

    The equation of simple harmonic motion is given by X = (4 cm)sin (6.25 t + 5π/3), then maximum velocity of the particle in simple harmonic motion is: 

    Solutions

     

  • Question 9/10
    1 / -0

    The time period of a simple pendulum in a stationary trolley is T1. If the trolley is moving with a constant speed, then time period is T2, then 

    Solutions

    The time period will remain the same as the acceleration of the trolley is zero in both the cases and the effective acceleration of pendulum remains the same.

     

  • Question 10/10
    1 / -0

    A particle executes S.H.M with a frequency of 20 Hz. The frequency with which its potential energy oscillates is:

    Solutions

    The frequency at which potential energy oscillates= 2 x frequency of oscillation

    = 2 x 20

    = 40 Hz.
