You have two metal spheres of radius $0\mathrm{.}1$mm located as shown. On sphere A you remove $9\mathrm{.}2*10^12$ ?electrons, while on sphere B you add $4\mathrm{.}2*10^13$ ?electrons. $1)$What is the charge on sphere A$?$B$?$ ?Draw the direction. Which sphere has the larger force? $2)$ ?Calculate the force on sphere A$.$
