Paragraph for Questions 10 - 12
In the graph shown, the potential energy of Earth-particle system is shown by a solid line as a function of distance r (the separation between Earth's centre and particle). The total energy of the two objects which may or may not be bounded to the Earth are shown in the figure by dotted lines. Based on the above information, answer the following questions:
If object having total energy E1 is having the same PE curve as shown in the figure, then
