If the magnitudes of both charges are tripled and their separation is also tripled, what happens to the magnitude of the electrostatic force that each charge exerts on the other

Answer:

The force remains the same

Explanation:

Originally;

Let the force on the charges be F1

distance of separation = r

magnitudes of the charges q1 and q2

K = Coulumb's constant

Hence;

F1= Kq1q2/r^2

Subsequently;

Let the force on the charges be F2

distance of separation = 3r

magnitudes of the charges 3q1 and 3q2

K = Coulumb's constant

Hence;

F2= K*3q1*3q2/(3r)^2

F2 = 9Kq1q2/9r^2

F2 = Kq1q2/r^2

Hence F1=F2
