A simple pendulum named Bob has a period of small oscillations T=1 s on Earth (assume g=9.80 ms2{“version”:”1.1″,”math”:”ms2″} ). Bob is flown to a planet X and it is found that now its’ period of small oscillations is 2 s. What is the value of specific gravity on the planet X in m / s 2 {“version”:”1.1″,”math”:”\mbox{m}/s^2″}?
