• question_answer A simple pendulum is suspended from the ceiling of a stationary vehicle, its time period is T. If the vehicle is moving with constant velocity, then time period of simple pendulum will be : A)  less than T 10     B)  equal to 2TC)  more than T       D)  unchanged

$T=2\pi \sqrt{\frac{\ell }{{{g}_{eff}}}};$ $\because$ vehicle is moving with constant velocity $\therefore$   ${{g}_{eff}}=g$  $\Rightarrow$    $T'=T$
