Explanation:
An open system is a system that has external interactions.
a closed system is a physical system that does not allow certain types of transfers in our out of the system.
an isolated system obeys the conservation law that its total energy- mass stays constant.
Answer:
Distance between both the object will be 404.51 m
Explanation:
We have given charge on two objects
Coulomb force between the two objects is given F = 5.5 N
We have to fond the distance between both the object so that force between them is 5.5 N
According to coulomb law force between two charge particle is
So
r = 404.51 m
So distance between both object will be 404.51 m
