GIVEN:
g'= gravity at height
g=9.8m/s²
Re=6400km
h=500km
CALCULATION
g'=g( 1+ 2h/Re)
g'= 9.8( 1+ 1000/6400)
g'=9.8(1+0.15625 )
g'=9.8 × 1.15625
ANSWER :g'=11.33125 m/s²

you know it very well that gravity follows inverse square law. so the acceleration due to gravity will decrease in this case. g1 is the acceleration due to gravity at the surface of the earth which is 9.8ms^2 r1 is the distance of the surface from the centre of the earth.
so the formula is :
g1/g2=(r2)^2/(r1)^2
now u can calculate it but Plugging this all in
g1=9.8ms^2
r2=6900km
r1=6400km
now u can calculate

g1/g2=(r2)^2/(r1)^2
