A $0\mathrm{.}026g$ plastic bead hangs from a lightweight thread. Another bead

is fixed in position beneath the point where the thread is tied. If both

beads have the same positive charge $q,$ the moveable bead swings

out to make the angle $=48$ and the distance $r=7cm$ as shown

in $($Figure $1).$
