What is the force between two small charged spheres that have charges of 2 x 10^7 and 3 x 10^7 if the distance of r is 30 cm.
I think you use Force = the constant of K multiplied by the product of the charges divided by the square of the distance again. If you plug in the numbers, you would get 6 x 10^7.
I am almost sure this is right, if you could please plug in the numbers and let me know if this is the answer because for some reason I can never get the right numbers even if I follow the right steps.
Please let me know if this is right.
As always, your help is very much appreciated.
=)
Thanks!
I once heard that those who help others, help themselves (its from the Bible) and that is so true!

You are correct. I will gladly critique your calculations.

actually, i think you have to convert cm to m. therefore, you would get 6 x 10^2 as an answer
