Two simple pendulums having lengths l_1 and l_2 with negligible string mass undergo angular displacements θ_1 and θ_2, from their mean positions,…
Two simple pendulums having lengths $\displaystyle l_1$ and $\displaystyle l_2$ with negligible string mass undergo angular displacements $\displaystyle \theta_1$ and $\displaystyle \theta_2$, from their mean positions, respectively. If the angular accelerations of both pendulums are same, then which expression is correct?
Official answer
From NTA’s final answer key for this paper.
(2)
$\displaystyle \theta_1 l_2=\theta_2 l_1$
