**1. Homework Statement**

Synchronus communications satellites are placed in a circular orbit that is 3.59 x 10

^{7}m above the earth's surface. What is the magnitude of the acceleration due to gravity at this distance?

F=?

G=6.67259 x 10

^{-11}N*m

^{2}/kg

^{2}

M

_{E}(Mass of Earth)= 5.98 x 10

^{24}kg

r = 3.59 x10

^{7}m

**2. Homework Equations**

F = (G*m

_{1}*m

_{2})/(r

^{2})

F = MA

**3. The Attempt at a Solution**

1) F = G * (M

_{E}

^{2}/r

^{2}) = 1.8514...N

2)F = MA --> (1.8514...N) = (5.98 x 10

^{24})A

3) A = 0.309 m/s

^{2}

CORRECT ANSWER: 0.233 m/s

CORRECT ANSWER: 0.233 m/s
