The force is
Explanation:
Two charged objects, of charge
distance r, exert a force on one another.
The magnitude of this force is given by, Coulomb's Law :
where k is a constant:
The direction of the force is toward the second object if the
objects have opposite signs, and away from the second
object if the signs are the same.
Here,
