Answer:
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 % .
