(D) The time period of a simple pendulum is given by the formula $T = 2\pi \sqrt{\frac{L}{g_{eff}}}$,where $L$ is the length of the pendulum and $g_{eff}$ is the effective acceleration due to gravity.When the van moves with a uniform velocity,its acceleration is zero.Therefore,the net force acting on the pendulum bob remains the same as when the van was stationary.Since the effective acceleration due to gravity $g_{eff}$ remains equal to the acceleration due to gravity $g$,the time period $T$ remains unchanged.

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