Simple Pendulum and Compound Pendulum

The time period of a simple pendulum is independent of

• Length of the pendulum

• Mass of the bob

• Acceleration due to gravity

• Diameter of the bob

The tension in the string of a simple pendulum is maximum, when the bob of the pendulum

• is at the extreme position

• midway between the mean position and extreme position

• is at the mean position

• starts oscillating with very large amplitudes

For small amplitudes, the force constant of a simple pendulum is

• directly proportional to the acceleration due to gravity

• inversely proportional to the acceleration due to gravity

• independent of the mass of the bob and the length of the pendulum

• directly proportional to the mass of the bob

A simple pendulum is kept oscillating in a lift. If the lift starts moving down with uniform velocity then the time period of the simple pendulum

• will increase

• will not change

• will decrease

• will be zero

The examples for periodic phenomena in nature are

• occurrence of day and night

• heartbeat

• rotation of the earth around the sun

• all of the above

The maximum displacement done by a vibrating body away from its original position is called

• Amplitude

• Frequency

• Time Period

• None of the above

The time is taken by the oscillating body to make one complete oscillation is called

• Crest

• Trough

• Time Period

• Velocity

When the axis of suspension of a compound pendulum passes through its center of mass

• the pendulum oscillates with the minimum time period

• the pendulum does not oscillate at all

• the pendulum oscillates for some time and gradually comes to rest

• All of the above

In a compound pendulum when the center of suspension and center of oscillation are equidistant from the center of mass

• the period of oscillation is minimum

• the period of oscillation is maximum

• the period of oscillation is equal

• none of the above

Which of the following shape of the body can be considered as a compound pendulum?

• Cylindrical

• Cubical

• Cuboidal

• Any rigid body
