T1 = 32 days 
T2 = 256 days
R1 = R 
R2 = ?
fraction numerator T subscript 2 superscript 2 over denominator T subscript 1 superscript 2 end fraction space equals space fraction numerator R subscript 2 superscript 3 over denominator R subscript 1 superscript 3 end fraction space R subscript 2 superscript 3 space equals space open parentheses 256 over 32 close parentheses squared R cubed subscript 1 space equals space 8 R cubed R subscript 2 superscript 3 space equals open parentheses space 2 R close parentheses cubed space R subscript 2 space equals space 2 R 
 Orbital radius of later is 2R

A boy throws a steel ball straight up. Consider the motion of the ball only after it has left the boy's hand but before it touches the ground and assume that forces exerted by the air are negligible. For these conditions, the force(s) acting on the ball is (are): a. A downward force of gravity along with a steadily decreasing upward force b. A steadily decreasing upward force from the moment it leaves the boy's hand until it reaches its highest point on the way down there is a steadily increasing downward force of gravity as the object gets closer to the earth c. Constant downward force of gravity along with an upward force that steadily decreases until the ball reaches it highest point on the way down there is only a constant downward force of gravity d. Constant downward force of gravity only
