Dear
Student,
Please find below the solution
to the asked query:
In the gravitational field, the expression for total mechanical energy in the case of a bounded body is,E=-GMm2rwhereM=Mass of the earthm=Mass of the bodyr=Distane between the centresFrom the above expression, it is clear that the total mechanical energy ofbounded system is negative
Ans: Option - B
