a particle is taken to height r above the earth surface where r is the radius of earth the accleration due to gravity is
 
 but according to me
 
the earth gravitation is same everywhere in the universe

Expert Answer:

Laws of gravitation (inverse square law) and Gravitational constant G are same everywhere in the universe. 
 
But gravitational force between two massive object depends on their respective masses and the distance between them
 
as per the inverse square law, gravitational force experienced by the mass m is begin mathsize 12px style F space equals space G fraction numerator m cross times M over denominator R squared end fraction space equals space m cross times fraction numerator G M over denominator R squared end fraction end style
so the term begin mathsize 12px style fraction numerator G M over denominator R squared end fraction end style is acceleration due to gravity and related to R which is radius of earth
