Because people do not like being told what to do.
Atoms with unbalanced electrical charges are called ions.
Those with positive charges are called cations.
Those with negative charges are called anions.
Answer:

Explanation:
The data given in the question is
Charge : q =
Electric field Strength : E = 
Electrical potential Energy : U = 
Let, the distance be "d"
So, the formula for Electrical potential energy is

Simplified formula for distance become

Now , insert the value

or,

Rounding off
