Two electrostatic point charges of +59.0 µC and +55.0 µC exert a repulsive force on each other of 153 N. What is the distance between the two charges? The value of the Coulomb constant is 8.98755 × 109 N · m2/C2. Answer in units of m.

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?
