WebDec 28, 2024 · Solution: Gravitational potential: V gravity = – GM/r = – (6.67 x 10 -11 x 5.97 x 1024 )/ (6371000) = 62.5×10 6 Joule/kg = 62.5 MegaJoule/kg 2 ) Taking the Earth’s surface as Vgrav = 0, what is the gravitational potential 2m above the ground? Solution: 3 ) A 0.2 kg firework reaches a gravitational potential relative to the ground of 500 Jkg−1. WebAnswer: The force exerted by a thin and strong string is distributed to very less area and hence the force applied due to the bag is more, the pressure exerted on the body by thin straps will be more and hence will be more painful. As pressure is inversely proportional to area, if the area is reduced pressure Questin 2.
