A. 2T B. OC. O D. C. T toT the new period of oscillation in terms of T (the period of The endulum onEownw inoing on a te ayon antow the pendulum on Earth). knowing that the gravity on Pluto is 1/16 that of Earth u. & v.- OPww.an·@i C19WSExplanation / Answer
T = 2 pi sqrt[ L / g ]
T is independent of mass.
hence time period will remain same.
Ans: T
---------------------
T = 2 pi sqrt[ L / g]
so T sqrt(g) = constant
T sqrt(g) = Tp sqrt(g/16)
T = Tp / 4
Tp = 4 T
