SUMMARY

The discussion focuses on calculating the charge of a sphere, specifically denoted as q2. Participants suggest using a diagram to visualize the problem and recommend writing out the equation that represents the sum of the charges. This approach is essential for determining the unknown charge based on the known values. The conversation emphasizes the importance of systematic problem-solving in electrostatics.

PREREQUISITES

Homework Statement
Two small spheres (q1& q2) have different charges that add up to 5.0x10^-5 C. If they repel each other with a force of Fe = 1.0 N at a distance of 2.0 m apart, what is the charge on q2?
Relevant Equations
Electric force formula

Fe= (k*q1*q2)/r^2

Electric Field Formula

E=(k*q1)/r^2

where k is a constant 9x10^9 N*m^2/kg^2
I drew a diagram using all of the information

however, I am stuck and not to sure how to get one of the charges

Try writing out the equation that says the charges add up to…

See if that gives you enough info.
