Identify correct statement among the following

  • A

    The greater the mass of a pendulum bob, the shorter is its frequency of oscillation

  • B

    A simple pendulum with a bob of mass M swings with an angular amplitude of ${40^o}$. When its angular amplitude is ${20^o}$, the tension in the string is less than $Mg\cos {20^o}$.

  • C

    As the length of a simple pendulum is increased, the maximum velocity of its bob during its oscillation will also decreases

  • D

    The fractional change in the time period of a pendulum on changing the temperature is independent of the length of the pendulum

The frequency of oscillation of a mass $m$ suspended by a spring is $v_1$. If length of spring is cut to one third then the same mass oscillates with frequency $v_2$, then

When a body of mass $1.0\, kg$ is suspended from a certain light spring hanging vertically, its length increases by $5\, cm$. By suspending $2.0\, kg$ block to the spring and if the block is pulled through $10\, cm$ and released the maximum velocity in it in $m/s$ is : (Acceleration due to gravity $ = 10\,m/{s^2})$

An assembly of identical spring-mass systems is placed on a smooth horizontal surface as shown. At this instant, the springs are relaxed. The left mass is displaced to the/left and theiright mass is displaced to the right by same distance and released. The resulting collision is elastic. The time period of the oscillations of system is

What is the period of small oscillations of the block of mass $m$ if the springs are ideal and pulleys are massless ?

A spring balance has a scale that reads from $0$ to $50\; kg$. The length of the scale is $20\; cm .$ A body suspended from this balance, when displaced and released, oscillates with a period of $0.6\; s$. What is the weight of the body in $N$?
