Vedclass · Answer

(B) The time period $T$ of a simple pendulum is given by the formula $T = 2\pi \sqrt{\frac{\ell}{g}},$ where $\ell$ is the length of the pendulum and $g$ is the acceleration due to gravity. From this formula,it is clear that $T \propto \frac{1}{\sqrt{g}},$ which means the time period decreases as $g$ increases and increases as $g$ decreases. At the top of a mountain,the height $h$ from the surface of the Earth is positive,and the acceleration due to gravity is given by $g_h = g_0 \left( \frac{R}{R+h} \right)^2.$ Since $g_h Because $g$ is smaller at the top,the time period $T$ will be larger at the top of the mountain compared to the base. Therefore,both Assertion $(A)$ and Reason $(R)$ are true,and $(R)$ is the correct explanation of $(A).$
