Part $3-$ Incorporating Other Types of Energy

Consider the following systems. Create models for them, making sure to draw energy bar charts. Provide equations for energy in symbolic form $($if you can$).$

$9.$ A balloon with charge $+q$ is placed directly above another balloon of charge $+q($on the floor$).$ The upper balloon is then released.

$10.$ A charged spherical ball of mass $m$ and charge $+q$ is floating horizontally towards another charged ball of equal mass and opposite charge through a viscous liquid.

$11.$ A mass $m$ with small positive charge $+q$ is placed on the level ground a distance $r$ away from a mass $M$ with a large negative charge $-Q$ and released. $($The masses feel kinetic friction with the ground.$)$

$12.$ A balloon with charge $-q$ is stuck to the wall. The balloon then slides down the wall to the floor.
