A simple pendulum, suspended from the ceilling of a stationary van, has time period T. If the van starts moving with a uniform velocity the period of the pendulum will be

  • Option 1)

    Less than T

  • Option 2)

    equal to 2T

  • Option 3)

    greater than T

Answers (1)

Effective value of 'g' remains unchanged.

 

Time period of pendulum of large length but small amplitude -

T= 2\pi \sqrt{\frac{1}{g\left ( \frac{1}{l}+\frac{1}{R} \right )}}

- wherein

l= length of pendulum

g= acceleration due to gravity.

R= Radius of earth

equal to 2T

This is incorrect.

Option 3)

greater than T

This is incorrect.
