Question:

A $4.0 \mathrm{mg}$ bead with a charge of $7.0 \mathrm{~cm}$ $2.5 \mathrm{nC}$ rests on a table. A second bead, FIGURE P20.62 with a charge of $-5.6 \mathrm{nC}$, is directly above the first bead and is slowly lowered toward it. What is the closest the centers of the two beads can be brought together before the lower bead is lifted off the table? image text in transcribed
