Good i’m tired how about you
Answer:
The separation between the charges was decreased by a factor of 0.2
Explanation:
The Coulomb's force between two charges is given by;

r₂ = 0.2r₁
Therefore, the separation between the charges was decreased by a factor of 0.2.
DRAG is the sum of all the aerodynamic or hydronamic forces in the direction of the external fluid flow.
I believe the answer is Ca
