Vedclass · Answer

(C) The time period of a simple pendulum is given by $T = 2\pi \sqrt{\frac{L}{g}}$.As we move to Mount Everest (higher altitude),the value of $g$ decreases.Since $T \propto \frac{1}{\sqrt{g}}$,a decrease in $g$ leads to an increase in the time period $T$.An increase in the time period means the clock takes more time to complete one oscillation,which implies the clock becomes slow,not fast.Therefore,Assertion $A$ is incorrect.The value of $g$ at altitude $h$ is $g' = g(1 - \frac{2h}{R_e})$,which is indeed less than $g$ at the surface. Thus,Reason $R$ is correct.Hence,$A$ is incorrect but $R$ is correct.
