3/19 Electric Charge and Force

Charged a balloon with different objects and then see if the balloon sticks to a uncharged object.

We used strips of Scotch tape to see how the strips with the same charge and with opposite charges reacted.

Here we derived an equation for the Force of a ball hanging from  a string with an angle theta.


This is our graph that we fit manually.


Calculations of electrical force of opposite charged particles.


Here we calculated the ratio between electrical force and gravitational force. Clearly this ratio how much stronger electrical charge is with equal distances. However, may not be true under extreme circumstances.
