The time period of oscillation of a simple pendulum of length L suspended from the roof of a vehicle, which moves without friction down an inclined plane of inclination $\alpha$, is given by :
Solution
<p>$\left| {{g_{eff}}} \right| = \left| {\overline g - \overline a } \right|$</p>
<p>$\Rightarrow {g_{eff}} = g\cos \theta$</p>
<p>$\Rightarrow T = 2\pi \sqrt {{l \over {{g_{eff}}}}}$</p>
<p>$= 2\pi = \sqrt {{L \over {g\cos \theta }}}$</p>
