Dialogue: 0,0:00:00.00,0:00:02.00,Default,,0000,0000,0000,,Well let's plug into this equation.
Dialogue: 0,0:00:02.00,0:00:07.00,Default,,0000,0000,0000,,When we carry out this multiplication, we get a result of -1.35 x10¹⁰ J.
Dialogue: 0,0:00:07.00,0:00:12.00,Default,,0000,0000,0000,,Now notice that this is a negative number and in fact, if r were smaller,
Dialogue: 0,0:00:12.00,0:00:16.00,Default,,0000,0000,0000,,so these were closer together, it would have been a more negative number.
Dialogue: 0,0:00:16.00,0:00:19.00,Default,,0000,0000,0000,,It would have been a lower potential energy.
Dialogue: 0,0:00:19.00,0:00:22.00,Default,,0000,0000,0000,,Now in genuine physics, objects like to be in a low energy state.
Dialogue: 0,0:00:22.00,0:00:27.00,Default,,0000,0000,0000,,Balls like to roll downhill and positive charges like to be with negative charges.
Dialogue: 0,0:00:27.00,0:00:31.00,Default,,0000,0000,0000,,And we can see in this equation that if one charge is positive and the other negative,
Dialogue: 0,0:00:31.00,9:59:59.99,Default,,0000,0000,0000,,well this energy will be negative, and this r want to be as small as it possibly can.
