Answer:
Step 1
The expression for the electric force between 2 charges is given as
F=k q1q2/r2
Here
F is the electric force
k is the coulombs constant
q1 is the charge on 1st particle
q2 is the charge on second particle
r is the distance the charges
Step 2
From the above expression we can clearly see that the force has the inverse relation with the square of distance between the charges. So if the distance between the charges increases, force will decrease.
Therefore, when the distance between the object increases, the magnitude of the force decreases.
Explanation:
X=7 and all the sides are equal so just plug it in to get 13
