Synchronous communications satellites are placed in a circular orbit that is 3.59* 10^7 m above the surface of the earth. What is the gravitational field strength at this height? (0.223 m/s^2) Gravitational field strength = g = GM/r^2 (the force it would exert per kilogram.)

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.
