A moon expands to 16 times its original radius while keeping the same mass. Which comparison is correct for ideal surface speeds?
A
Escape speed becomes 1/16 of the original, but circular orbital speed is unchanged.
B
Escape speed becomes 16 times larger because the radius is larger.
C
Escape speed stays the same because the mass is unchanged.
D
Both surface escape speed and surface circular orbital speed become 1/4 of their original values.
