Find the charge of the sphere (q2)

In summary, to find the charge of a sphere, you can use the formula q = ke * (q1 / r^2), where q is the charge of the sphere, ke is the Coulomb's constant, q1 is the charge of the other object, and r is the distance between the two objects. The unit of measurement for charge is called the Coulomb (C), which is a derived unit in the International System of Units (SI). The charge of a sphere can be negative or positive, depending on the excess or lack of electrons in the sphere. The distance between two objects has an inverse relationship with the charge of a sphere, and other factors such as size, material, and external influences can also affect the charge

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.
