Q2. On the planet Newtonia, a simple pendulum having a bob with a mass of1.27 kg and a length of 187.0 cmtakes142 sec, when released from rest, to swing through an angle of 13.5 degrees, where it again has zero speed. The circumference of Newtonia is measured to be 51500 km.
What is the mass of planet Newtonia?
