If the force is 4 newtons between two charged spheres separated by 3 centimeters, calculate the force between the same spheres separated by 6 centimeters.

2 N

0.3 N

6 N

1 N

1 Newton

Explanation:

F=9*10^9*q0q1/r^2]]

F=9*10^9 * (q0q1) / r^2

r=3cm

F=4N

F=9*10^9 * (q0q1) / 3^2

4=9*10^9 * (q0q1) / 9

4=10^9 q0q1

q0q1=4/10^9

q0q1=4*10^-9

To calculate the force between the forces at a distance of 6 cm

F=9*10^9 * (q0q1) / r^2

=9*10^9 * (4*10^-9) / 6^2

=9*10^9 * (4*10^-9) / 36

=10^9*4*10^-9/4

=10^9*10^-9

=1 Newton
