An oscillating simple pendulum of time period $\displaystyle \mathrm{T}_{\mathrm{o}}$ is placed in a lift which is accelerating upwards with $\displaystyle 2.5 \mathrm{~m} / \mathrm{s}^2$. The time period of pendulum in the lift will be (if $\displaystyle \mathrm{g}=10 \mathrm{~m} / \mathrm{s}^2$ )
Official answer
(2)
$\displaystyle \frac{2}{\sqrt{5}} \mathrm{~T}_{\mathrm{o}}$
