Question

There are two identical, positively charged conducting spheres fixed in space. The spheres are 35.8 cm apart (center to center) and repel each other with an electrostatic force of $F_1 = 0.0675$ N. A thin conducting wire connects the spheres, redistributing the charge on each sphere. When the wire is removed, the spheres still repel, but with a force of $F_2 = 0.115$ N. The Coulomb force constant is $k = frac{1}{4piepsilon_0} = 8.99 imes 10^9$ N $cdot$ m$^2$/C$^2$. Using this information, find the initial charge on each sphere, $q_1$ and $q_2$, if $q_1$ is initially less than $q_2$. $q_1 = 3.32 imes 10^{-7}$ $q_2 = -2.89 imes 10^{-6}$
