Answer:
Product
Explanation:
The force between two charges is given by :
[tex]F=\dfrac{kq_1q_2}{r^2}[/tex] ...(1)
Where
k is electrostatic constant
q₁ and q₂ are charges
r is the distance between charges
From equation (1), it is clear that the magnitude of the force is directly proportional to the product of charges.
