It is easiest in free space, where observations may and can be made?

A
g=L3=0
B
g=3L=a
C
g=a3L=0
D
g=L3=∞
Answer
g=a3L=0
Explanation
Solution
In free space, the acceleration due to gravity (g) is ideally zero. For observations to be "easiest," objects should also not be subjected to other accelerations (a) from external forces. Option 3 states g=0 and a3L=0. Assuming L is a non-zero physical length, a3L=0 implies a=0. Therefore, option 3 represents the ideal conditions of zero gravitational acceleration and zero external acceleration, making it the most suitable answer for "easiest observations in free space."
