Question

The bob of a simple pendulum is displaced from its equilibrium position O to a position Q which is at height h above O and the bob is then released. Assuming the mass of the bob to be m and time period of osciliations to be 2.0 sec. the tension in the string when the bob passes through O is

• A. $m(g+\pi \sqrt{2gh})$
• B. $m(g+\sqrt{{\pi }^{2}gh})$
• C. $m(g+\sqrt{\frac{{\pi }^2}{}gh})$
• D. $m(g+\sqrt{\frac{{\pi }^2}{3}gh})$
