What percentage of the acceleration at Earth's surface is the acceleration due to gravity at the position of a satellite located 489 km above Earth

Explanation:

The formula for variation in the value of g due to height h is given by the following relation .

g₁ = g₀ ( 1 - h / R )

g₁ and  g₀ are value of acceleration due to gravity at height h from surface and at surface and  R is radius of the earth .

R = 6370 km , h = 489 km ( given )

g₁ = g₀ ( 1 - 489 / 6370 )

= .923 g₀

g₁ in percent terms = .923 x 100

= 92.3 % .

explanation:

newton's third law, for every action there is an equal and opposite reaction.
