Question
Need help solving for the magnitude!
The diagram below shows two charged spheres. The spheres e held in place by insulating strings which are not shown in the diagram. The left sphere has a net charge of -20 nC and the right sphere has a net charge of +5 nC. Add two arrows to the diagram correctly representing the electrical force on each sphere due to the other. Make sure your arrows properly show both the direction and correct relative magnitudes of the two forces (longer arrows represent forces of larger magnitude).Explanation / Answer
we know that opposite charge attract each other hence there is an attraction force between them. This force direction will be opposite for each of the charge towards each other.but the magnitude will be same.
F = kQ1Q2/r2
here Q1 = -20 nC
Q2 =+5 nC
But r is not given
hence if r is given, then we can calculate the force
