Electric Charge given two forces and distance

Click For Summary
SUMMARY

The discussion centers on calculating the initial charges on two identical positively charged conducting spheres that repel each other with forces F1=0.0615N and F2=0.100N after connecting them with a conduction wire. The Coulomb Force constant is specified as k=8.99*10^9 N*m^2/C^2. The user attempted to apply Coulomb's Law, F=(k*q1*q2)/r^2, but encountered issues with charge cancellation, indicating a misunderstanding of the charge redistribution process. The correct approach involves recognizing that the charges redistribute equally when connected by the wire, leading to a new force calculation.

Homework Statement



There are two identical, positively charged conducting spheres fixed in space. The spheres are 38.2 cm apart (center to center) and repel each other with an electrostatic force of F1= 0.0615N. Then, a thin conduction wire connects the spheres, redistributing the charge on each sphere. When the wire is removed the spheres still repel but with a force of F2=0.100N. Using this information, find the initial charge on each sphere, q1 and q2 if initially q1<q2. The Coulomb Force constant is k= 8.99*10^9 N*m^2/C^2

Hint: Assume the spheres are in a one-dimensional plane to simplify the calculation.

Homework Equations



Coulombs Law: F=(k*q1*q1)/r^2

The Attempt at a Solution



I set up coulombs law equation and solved for q1, then plugged it back into the equation, but all the charges canceled out

and I was left with F1=F2, which isn't true in this scenario. I'm stuck and have no idea what to do. Any insight would be greatly appreciated!
