Ok this is the question in text book i cant figure out.(adsbygoogle = window.adsbygoogle || []).push({});

"The force of repulsion that two like charges exert on each other is 3.5N. What will the force be of the distance between the charges is increased to fice times its orginal value ? "

im a physics moron , treat me like one :rofl:

ok i understand that two like charges will repluse.

In this case its at 3.5N. So i was thinking that if the force of it was at 3.5N and the distance was increased by 5x then just multiply 3.5N x 5 = 17.5 which when i check in back off the book is wrong. Can you help explain this to me so i can understand it ? The answer the book has is 0.14N
