The binding energy of a satellite of mass m in a orbit or radius r is (R = radius of earth, g= acceleration due to gravity)

The binding energy of a satellite of mass m in a orbit or radius r is

1.	The binding energy of a satellite of mass m in a orbit or radius r is (R = radius of earth, g= acceleration due to gravity)
Answer» `(mgR^(2))/(r )` `(mgR^(2))/(2R )` `-(mgR^(2))/(r )` `-(mgR^(2))/(2r )` ANSWER :B
