Two balloons have equal and opposite charges. Balloon one has $N={10}^8$ excess electrons. The balloons are separated by $d=2\mathrm{.}6m$ and each electron has a negative charge of $e=1\mathrm{.}602{10}^{-19}C.$

Part $($a$)$

What is the charge on balloon two, $Q_2,$ in C $?$

Part $($b$)$

What is the magnitude of the force $($in N $)$ of balloon one on balloon two using the variables provided and the Coulomb constant $).$

$F_{12}=$
