repeated mesurement can reduce the error
it is true
if you take any mesurement repeatedly and the average is taken, the error will be less

Answer:
Acceleration due to gravity, 
Explanation:
It is given that,
Mass of Pluto, 
Distance between Neptune and Pluto, 
The force of gravity is balanced by the gravitational force between Neptune and Pluto. It is given by :



So, the acceleration due to gravity at Neptune due to Pluto is
. Hence, this is the required solution.
I think it’s, its direction would reinforce the original movement
