Answer:
B)
Explanation:
The electric force between charges can be determined by;
F =
Where: F is the force, k is the Coulomb's constant, is the value of the first charge,
is the value of the second charge, r is the distance between the centers of the charges.
Let the original charge be represented by q, so that;
= 2q
=
So that,
F = x
= 2q x x
= x
= x
F = x
The electric force between the given charges would change by .
