Asked by Jose
two point charges have a total charge of 277 µC. When placed 2.00 m apart, the force each exerts on the other is 20.8 N and is repulsive.
what are the charges on both?

Let the two charges be Q1 and Q2
Q1 + Q2 = 277 µC
k*Q1*Q2 /R^2 = 20.8 Newtons
Two equations; two unknowns.
k is the Coulomb constant. Look it up if you need to.
R = 2.00 m
Take it from there; it's just algebra.
