Electrostatic Equilibrium

20. A poor monkey spends his last nickel on two magic bananas. When he dangles the two
9/3-kg (which is heavy because the magic bananas are made out of metal) bananas from
cords, they "magically" spread apart as shown below. Actually, it's because they have equal
electric charge.
