A man measures the period of a simple pendulum inside a stationary lift and finds it to be

T

second. If the lift accelerates upwards with an acceleration g/4, then the period of pendulum will be

View answer and explanation

Correct option: C

\frac{{2T}}{{\sqrt 5 }}

Option C (

\frac{{2T}}{{\sqrt 5 }}

) is correct because the time period decreases when the lift accelerates upwards.

Assertion: A particle executing simple harmonic motion comes to rest at the extreme positions.

Reason: The resultant force on the particle is zero at these positions. A particle is subjected simultaneously to two SHM’s one along the

x

-axis and the other along the

y

-axis. The two vibrations are in phase and have unequal amplitudes. The particle will execute A particle is executing SHM with amplitude

When the PE of a particle is one-fourth of its maximum value during the oscillation, its displacement from the equilibrium position will be The displacement, velocity and acceleration in a simple harmonic motion are related as the Assertion: Angular velocity of earth around sun is lesser than the angular velocity of moon about earth.
Reason: Time taken by moon revolve around earth is less than time taken by earth to revolve around sun. A particle is executing
