In the graph shown, the `PE` of earth-satellite system is shown by a solid line as a function of distance `r` (the separation between earth's centre and satellite). 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.
Mark the correct statement(s).

Options

A. The object having the total energy `E_(1)` is bounded one.
B. The object having the total energy `E_(2)` is bounded one.
C. Both the objects are bounded
D. Both the objects are unbounded

Answer

A

Explanation

For the system to be bounded one, total energy of the system must be negative. So, object having total energy `E_(1)` is bounded and other is unbounded.
